- Due to continuous improvement, all specifications are subject to change without notice. The 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 700 nm and for basic system without options.
- Optional signal extended range: 660 – 1320 nm.
- When extended signal range is selected.
- See tuning curves for typical outputs at different wavelengths.
- At 700 nm or higher wavelengths.
- When wavelength is controlled from PC. When wavelength is controlled from keypad, tuning resolution is 0.1 nm for signal,
- 1 nm for idler and 0.5 nm for SH.
- FWHM measured with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.
- Beam diameter is measured at 700 nm at the 1/e2 level and can vary depending on the pump pulse energy.
- Full angle measured at the FWHM level at 700 nm.
- Separate output port for the 532 nm beam is standard. Output for 1064 nm beam is optional. Pump laser output will be optimized for the best OPO operation and specification may vary with each unit we manufacture.
- Air cooled power supply is available as option.
- Mains voltage should be specified when ordering.
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.
