1.1 Distributed Feedback Single Frequency Fiber Laser

Low-Linewidth, Low-Noise, No Mode-Hopping, Wavelength Tunable, Linear-Polarization

Single-frequency fiber laser has the greatest advantage of high-purity single-frequency laser outputting with narrow-linewidth. Single-frequency fiber laser offered by us uses the technology of distributed feedback to generate linearly polarized single frequency laser in an all-fiber structure. The single-frequency operation is stable and efficient by adopting unique side frequency suppression technology. A special assembly structure is also used to isolate the impact of external environmental vibration and temperature changes, thereby effectively improving the long-term stability on frequency and narrowing the linewidth. Also in this way, the laser mode will never be hopped. At present, the average output power is greater than 10 mW, 40 mW and 10 mW at the band of 1 μm, 1.5 μm and 2 μm, respectively. The output wavelength is flexible and the linewidth is always less than 20 kHz. The wavelength thermal tuning range is as high as 0.8 nm and the fast frequency tuning range can reach 3-5 GHz. The laser also has good power stability (RMS<0.5% @3 hrs) and excellent beam quality (M2 <1.05). Therefore, the single frequency fiber laser offered by us is the best choice for cold atom physics, high power laser system, sensing and lidar applications.

3. SPZ Series Single Frequency Converted Lasers

High Power, Low Noise, Narrow Linewidth, Without Mode-hop, Tunable, Linear Polarization

Narrow-linewidth continuous-wave (CW) lasers at visible or ultraviolet (UV) wavelengths have various important applications in the fields of atomic and molecular physics, measurement, communication, biology, etc. In the quantum simulation experiment, high-power 532nm lasers with ultra-low frequency noise can be operated as optical lattice trap, providing enough trap depth for ultra-cold atoms and improving the signal-to-noise ratio of atoms. Besides the visible lasers, high-power CW ultraviolet lasers have been widely needed in the experiments of laser cooling, clock frequency detection, ionization, etc. For example, the long-range interaction of Rydberg atoms has a great advantage in quantum information, Rb can be excited to Rydberg state by single-photon process with 297 nm. The logic ion 9Be+ should be cooled with 313 nm in quantum simulation, and could be used for cooperative cooling of 27Al+ in the optical clocks. In the lithographic process, 390 nm at watt level can obviously reduce the exposure time. We provide total solutions for the needs of wavelengths. The standard frequency converted schemes include single-passing second harmonic-generation (FL-SSHG), single-passing third-harmonic-generation (FLSTHG), single-passing sum-frequency-generation (FL-SSFG), single-passing difference-frequency-generation (FL-SDFG), second-harmonic-generation (FLRSHG) and forth-harmonic generation (FL-FHG) in resonant cavities. With these nonlinear-processes, we can almost achieve wavelength from 266 nm to 4000nm.

Center frequency drift of 0℃ -50℃ is about 340 MHz, and the center frequency drift of 25℃ for 2 hours is about 40 MHz

The experiment of high and low temperature impact storage at -30℃ -70℃ showed that the laser normal operation after high and low temperature shock.

  • RMS power stability under high and low temperature impact

When the ambient temperature changes from 0℃ -50℃ at interval of 10 ℃. Although the laser power will jump during the temperature change process the power will remain stable at each temperature.

The stability of the first channel at each temperature point in the high-low temperature test was measured. The power stability of the 2-hour RMS at the limiting temperature of 0℃ and 50℃ was better than 0.2%. The power stability of the second channel is also better than 0.2% (single temperature point, RMS)

  • Frequency tuning test

The seed has a reserved frequency sweep interface, and the 780nm laser frequency sweep range is about 3.2GHz.

Selecting a reasonable frequency locking point and controlling an appropriate frequency difference and frequency shift between the two channels, a dualchannels.780 nm laser can provide all the lasers required for the experiment of rubidium atomic gravimeter. The product has good environmental adaptability and is an excellent choice for laser source of transportable atomic gravimeter.

4.6  780nm laser frequency locking module

Cold atom experiments with Rb need lasers with specific frequency and we launch different frequency locking schedules for 780nm laser. We built up an all-fiber-connected frequency locking module with an integrated optical system and other optical fiber devices. This module can offer stable SAS or MTS signal and together with our laser controller, frequency locking with good long-term stability is realized. The frequency difference between two lasers should keep to a constant value in some cold atom experiments. For 87Rb atom gravimeter, the frequency difference of cooling laser and repumping laser should be about 6.6GHz and for the two Raman lasers the value is 6.834GHz. We have launched a specialized laser controller for offset frequency locking in the range from 50MHz to 8GHz with beat frequency/phase locking technique.

(1) Integrated optical module

With integrated spatial frequency-locking module, we build an all-fiber-connected frequency locking module. This module gives a stable SAS or MTS signal at Rb D2 line and the spectrum can offer error signal for frequency locking of 780nm laser

Dimensions of integrated frequency-locking optical module

SAS and MTS signal from the integrated optical module

(2)  Multi-function laser controller

We offer a multi-function laser controller for frequency locking under different condition. The controller is integrated with modem, PID module and High-Voltage amplifier and it can work as error signal generator, PID servo and PZT driver at the same time. All functions are controlled by software with no physical button or knob. The controller can work in different mode under customized. Under internal-modulation mode laser is locked with SAS or AS while under external-modulation mode laser is locked with MTS or PDH technique.

Front panel of controller

(3)   SAS-Locking

Frequency locking with SAS is based on Lock-in amplifier. Take the SAS of 85Rb atom as example, the controller get SAS signal from integrated optical module and generate error signal with lock-in amplifier, the PID module in the controller will then lock the frequency of 780nm laser.

SAS and error signal in our software

We build two independent SAS-locking system for 780nm Laser and take a laser beating test with their 1560nm seed laser. This can show the stability of frequency locking.

(4)   MTS-Locking

Unlike SAS-locking, MTS-Locking is under extern-modulation mode and the spectrum signal getting from demodulation can directly serve as error signal. Also take the MTS of 85Rb atom as example, integrated optical module provide both SAS signal and modulated MTS signal to the controller. After demodulation, the MTS signal will be error signal for frequency locking while the SAS signal here will be a reference signal. Due to their different principles, locking point of MTS and SAS are not the same.

SAS (reference) signal and MTS (error) signal in our software

Take also the beating test with two independent MTS-locking module.

(5)   Beat phase/frequency locking module

Beat phase/frequency locking module is used for frequency locking of multi-lasers. We has launched a frequency control system for dual-channel 780nm laser device which serves as the laser source of 87Rb gravimeter and gradiometer. Frequency of channel1 is locked to the resonance peak with MTS-locking while channel2 is locked 6.834GHz offset from channel1 with beat phase locking. This dual-channel laser can offer almost all the laser that is needed for a 87Rb gravimeter.


  Error signal and output signal in our software

Beat phase/frequency locking is realized with our controller. A fast PD measures the beat signal between two lasers and the PFD module in our controller generates error signal with the beat signal and a reference signal, the laser frequency will then be locked by PID module.

The 3.4 GHz beat signal from two 1560nm lasers

For 87Rb atom gravimeter, frequency chirping or jumping of laser is needed. A typical example is the Raman lasers whose frequency need to change within 3 pulses to compensate the doppler effect. Our controller provides frequency jumping function with a switching time below 10 μs.
