For generating high peak power ultraviolet pulses of a few hundred picoseconds, microchip lasers are economical, compact, and reliable. Micro-joule UV pulses are generated by harmonic conversion of the IR passively Q-switched Nd:YAG engine. Microchips are also easy to operate and service ; controllers can be used with every laser head model and swapped within minutes while conserving constant performances. The SNV and SNU series are designed for high average power, delivering multi-kW peak power at repetition rates up to 20 kHz.

NOTES
(1) Measured with 1Ghz photodiode and 1GHz/10GS/s oscilloscope.
(2) Measurement performed with an OPHIR thermal power sensor (OPHIR 3A-FS-SH)
(3) For temperature variation < ± 3°C and < 3°C/hour, stability is measured with calorimeter - detector band [DC, 2Hz]
(4) Mean average value M = √(XY), X and Y being respectively the major and minor axis of the ellipse
(5) Beam exhibits different profile in horizontal (Gaussian) and vertical ((sin x /x)² in far-field) plan
(6) 5%/95% diameter, at 300mm from laser output
