And find more about the full characterization of two versions of our lasers: STMH-1550 at 1 GHz laser and STMH-1550 at 250 MHz.
It is the first industrial-grade laser of its kind that operates at telecom wavelengths and achieves the lowest phase noise and timing jitter on the market. In this document, we report the full characterization of the product operating at a repetition rate of 1 GHz.
Key product specifications
Frep: 1 GHz
Power: > 50 mW
λ0 : 1545 – 1565 nm
Clean soliton pulse
Bandwidth: > 10 nm
Pulse width: < 250 fs (Transform limited)
Sech2-shaped spectrum
Beam characteristics: TEM00, M2 < 1.05
Noise characterization (Free-running)
The free-running phase and amplitude noise of a STMH-1550 at 1 GHz is reported here. The phase noise was measured on the 10th harmonic, i.e., at 10 GHz.
