The DPSS CW deep UV Laser series FQCW-266 comes with a resonant frequency conversion stage, emitting a fixed wavelength of 266 nm. 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, no other provisions (chiller, fan etc.) are needed. The FQCW266-series of DPSS CW deep UV lasers deliver up to 500 mW at 266nm in single frequency operation. Compared to other CW lasers at 266 nm, the FQCW266 systems have a long coherence length of more than 1000 m, narrow line width (<300 kHz), low power consumption and a small footprint. The FQCW-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 0.8 mrad (full angle), low intensity noise below 0.5%rms (100 kHz-10 MHz) and a good power stability (<1% in 8 hours). These CW laser units are the proper tools for applications as Raman Spectroscopy, Wafer inspection and Photoluminescence where a long coherence length is required.
These UV CW lasers provide excellent beam quality and performance and are designed to meet the challenging demands of industrial use and intensive R&D.
