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) Tuning range of 210-405 nm is provided by NT242-SH/SFG.
3) See tuning curves for typical outputs at other wavelengths.
4) Inquire for other pulse repetition rates.
5) 100 Hz version is available. Pulse energy specification is >0.9 mJ at 450 nm.
6) FWHM measured with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.
7) Linewidth is <8 cm-1 for 210-405 nm range.
8) Beam diameter is measured at 450 nm at the FWHM level and can vary depending on the pump pulse energy.
9) Separate output port for the 3rd harmonics beam is standard. Output ports for other harmonics are optional.
10) The laser max pulse energy will be optimized for best OPO performance. The actual pump laser output can vary with each unit we manufacture. |
