SPECIFICATIONS Central wavelength (nm) Output average power (mW) Transverse mode Operating mode Single pulse energy (µJ) Near TEM00, elliptical Pulsed, Cr : YAG passively Q-switched 0.1~4 Pulse duration (ns) Peak power (W) ~10 ~400 Setting up one fixed rep. rate internal between 10kHz-15kHz with stable pulse energy, pulse duration and pulse period. 3kHz-5kHz by external trigger with stable pulse energy, pulse duration and pulse period. QCW state with one rep. rate between 3kHz-5kHz. LD PUMPED ALL-SOLID-STATE UV LASER All solid state 257 nm UV laser is made features of ultra compact, long lifetime, cost -effectiveness and easy operating, which is widely used in UV curing, micro-electronics, CD carving, laser medical treatment, scientific experiment, etc. Average power (mW) Ave power stability (over 4 hours) Average power (mW) = Single pulse energy (µJ) * Rep. rate (kHz) <10% Beam parameters Warm-up time (minutes) Elliptical (4:1), Beam spot 0.5*2mm <10 Beam height from base plate (mm) Operating temperature (℃) Power supply (90-264VAC) Cooling system Expected lifetime (hours) Warranty period 1 year Please Note: because of the Walk-off effect of Nonlinear crystals, the beam quality of UV laser is not so good as that of 1064/532nm laser.
