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 3000 nm for NT377 unit, at 1570 nm for NT373 unit and at 7.0 μm for NT373-XIRx units.
2) The number represents available output wavelength range. Three standard options are available with 4.1-6, 6-12 and 5-11 μm tuning ranges.
3) Output is specified at wavelengths defined in chapter 1. See tuning curves for typical outputs at other wavelengths.
4) Linewidth is specified at wavelengths defined in chapter 1. See graph below for typical linewidth at other wavelengths.
5) Estimate, assuming that pulse duration from OPO is by approx 1 ns shorter than one from pump laser.
6) Beam diameter is measured at the FWHM level at the output aperture and can vary depending on the pump pulse energy.
7) Laser output will be optimised for OPO operation and specification may vary with each unit we manufacture.
8) Air cooled power supply is available as option.
9) For 10 Hz PRR.
10) Should be specified when ordering. |
