SFQCW-266nm Series CW Single-frequency DPSS Lasers

The DPSS CW deep UV laser series SFQCW-266, diode pumped continuous wave solid state laser, comes with a resonant frequency conversion stage, emitting a fixed wavelength of 266nm. The laser head is contained in a sealed aluminium housing, which allows operation in a wide range of environmental conditions. Heat removal from the laser head is done by air convection.

The SFQCW-266 plug & play laser comes with a control unit, allowing either push button control or remote control operation via serial (RS232 & USB) interface. The lasers offer excellent beam quality with an M2 below 1.3 , beam divergence below 0.8mrad (full angle), low intensity noise below 0.5% rms (100 kHz-10MHz) and a good power stability (<1% in 8 hours). These CW laser units are the proper tools for industrial use and intensive R&D applications as Raman Spectroscopy, Wafer inspection and Photoluminescence where a long coherence length is required.DPS lasers
