1) All specifications are subject to change without notice. Parameters marked ‘typical’ are indications of typical performance (not specifications) and will vary with each unit we manufacture. Unless stated otherwise, all specifications are measured at 1064 nm.
2) Inquire for custom pulse repetition rates.
3) Tuning range extension to 620 nm is optional.
4) Output powers are specified at selected wavelengths. See typical tuning curves for power at other wavelengths.
5) Measured at 800 nm for PT25x models, and at 1620 nm for PT277 model.
6) Measured at 400 nm.
7) Pulse duration can vary depending on wavelength and pump energy.
8) Beam diameter at the FWHM level and can vary depending on the pump pulse energy.
9) Full angle measured at the FWHM level.
10) Separate output port for the pump beam is standard. Output ports for other available harmonics are optional.
11) Data represents typical values. Laser output will be optimised for OPO operation and specification may vary with each unit we manufacture.
12) Measured at 1064 nm. |
