1) Due to continuous improvement, all specifications are subject to change. Parameters marked typical are illustrative; they are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise, all specifications are measured at 1064 nm.
2) Harmonics outputs are not simultaneous; only single wavelength beam is present at the output at once. Manual reconfiguration is required to switch wavelength.
3) Standard deviation value averaged from pulses, emitted during 30 sec time interval after 20 minutes of warm-up.
4) Deviation from average value measured over 8 hours of operation when room temperature variation is less than ±2 °C.
5) FWHM. Measured with photodiode with 100 ps rise time and oscilloscope with 600 MHz bandwidth.
6) Standard deviation value, measured with respect to triggering pulse.
7) Beam diameter is measured at 1064 nm at laser output at the 1/e² level.
8) Full angle measured at the 1/e² level at 1064 nm.
9) Mains voltage should be specified when ordering.
