Nanosecond Dye Laser: the ND6000

The ND6000 is a high energy, tunable dye laser, combining high performance with ease of use. Its proprietary, grazing incidence oscillator and transverse pumped amplifiers result in high efficiency, low amplified spontaneous emission (ASE), and linewidth of < 0.05 cm-1 at 560 nm. Its revolutionary circulator permits quick and easy dye changes. The laser tunes from 200 nm to 900 nm with the help of a crystal tracking option which electronically tunes the UVX wavelength extension packages. Grating options can provide narrower bandwidths and also extend the tuning range further into the infrared.

UV Frequency Extensions

Our UV extension packages use doubling, mixing, and mixing-after-doubling crystals to extend the wavelength range of our tunable dye and OPO sources into the UV. All UVX options are used to double, mix and/or mix after doubling the output of the ND6000 dye laser. The UVT options contain the automatic trackers which keep the crystals optimally tuned while the dye laser scans over a range of wavelengths.
