SNG High Performances Green Microchip Series
KEY FEATURES
• Repetition rate up to 70 kHz
• Ultrashort pulses down to 500 ps
• Multi-kW peak power
• Excellent beam quality – TEM00, M²<1.1
• Efficient, air-cooled
• Sealed package, extremely long life
For generating high peak power green pulses of a few hundred picoseconds, microchip lasers are economical, compact, and reliable. The 532nm pulses are produced by harmonic conversion from the IR systems, the same compact sealed package being used for either wavelength.
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 SNG series are designed for high average power, delivering multi-kW peak power at repetition rates up to 70kHz.
APPLICATIONS
• Material processing - Cost effective marking solutions - Graphitization
• Instrumentation - Ranging - Differential absorption LIDAR - Super-continuum generation - Distributed temperature sensing - Raman spectroscopy
• Biophotonics - Nanosurgery - Protein cross-linking

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 ellipticity is calculated as the ratio of the main axis far field divergence
