HIGH POWER SINGLE MODE SINGLE FREQUENCY 351 nm & 355 nm UV FIBER LASERS
Fiber Laser UV 351 and UV 355 CW
ALS-351 series is a range of high power, high brightness fiber lasers. with long coherence length and high polarization ratio.
Based on patented technology and major advances in fiber and system design, our fully integrated laser platform offers diffraction limited output powers in excess of 25 mW.
Our ultra-low noise fiber laser technology is particulary interesting for the most demanding application requiring an excellent stability in terms of power, pointing or frequency.
A full spectral control of the output is possible with linewidths down to less than 500kHz (single longitudinal mode) and a drift of the central wavelength down to less than 0.2pm over several hours.
The passive optical head avoids any heat generation (no fan, no chiller) to offer the best performances and an easy integration.
Fiber recoupling are available as an option.
