1) All specifications are subject to change without notice. Parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise, all specifications are measured at 450 nm.
2) Hands-free tuning range is from 192 nm to 2600 nm.
3) Tuning range extension to 400-709 nm is optional.
4) Measured at 450 nm. See tuning curves for typical outputs at other wavelengths.
5) Measured at 260 nm. See tuning curves for typical outputs at other wavelengths.
6) Measured at 340 nm. SF generator is optimized for maximum output in 300‑409 nm range. See tuning curves for typical outputs at other wavelengths.
7) Measured at 200 nm.
8) Linewidth is <8 cm-1 for 210-409 nm range.
9) Represents wavelength change quantum for manual input from control pad. When wavelength is controlled from PC, the wavelength set precision is ~1 cm-1 in OPO range and ~2 cm-1 in SH/SFG range.
10) FWHM measured with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.
11) Beam diameter is measured at 450 nm at the FWHM level and can vary depending on the pump pulse energy.
12) Full angle measured at the FWHM level at 450 nm.
13) Separate output port for the 355 nm beam is standard. Outputs for 1064 nm and 532 nm beams are optional. Laser output will be optimised for OPO operation and specifications may vary with each unit we manufacture.
14) 30 Hz version is available. Inquire for pulse energy specifications.
15) Version with DUV generator has dimensions of 446×260×1020 mm (W×H×L).
16) At 10 Hz pulse repetition rate. Air cooled power supply is available.
17) At 10/20 Hz pulse repetition rate.
