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 3000 nm for NT277, NT277-XIR unit and at 7000 nm for NT277-XIR units and for basic system without options.
2) Available wavelength range. Custom tuning ranges are available.
3) Inquire about tuning curves for typical outputs at other wavelengths.
4) Higher energy 10 – 150 cm⁻¹ option is available for 2500 – 4475 nm tuning range.
5) For manual input from PC. When wavelength is controlled from keypad, tuning resolution is 1 nm.
6) Measured at the wavelength indicated in the “Pulse energy” specification row.
7) Beam diameter is measured at the 1/e² level at the laser output and can vary depending on the pump pulse energy.
8) The laser max pulse energy will be optimized for best OPO performance. The actual pump laser output can vary with each unit we manufacture.
9) Measured at FWHM level with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.
PERFORMANCE
ORDERING INFORMATION
Note: Laser must be connected to the mains electricity all the time. If there will be no mains electricity for longer that 1 hour then laser (system) needs warm up for a few hours before switching on.
