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 1064 nm.
2) Available wavelength range. Standard tuning range options are 4.1-6 μm or 6-12 μm. Custom tuning ranges are available.
3) Inquire about tuning curves for typical outputs at other wavelengths.
4) Inquire for other pulse repetition rates. For some models up to 20 kHz PRR is possible.
5) 30, 50 and 100 Hz versions are available. Pulse energy specification is >9 mJ at 450 nm at 50 Hz.
6) 500 Hz version is available for higher pulse energy.
7) <10 cm⁻¹ option is available for whole tuning range.
8) Measured at the wavelength indicated in the “Pulse energy” specification row.
9) Ask for the separate NT240 series brochure.
10) Beam diameter is measured at the FWHM level at the laser output and can vary depending on the pump pulse energy.
11) Separate output port for the pump beam is standard. Output ports for other available harmonics are optional.
12) The laser max pulse energy will be optimized for best OPO performance. The actual pump laser output can vary with each unit we manufacture.
13) FWHM measured with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.
