Tunable laser system EKSPLA NT 342B-10-H-FC-ATTN  works with parametric oscillator OPO, pulse excitated at 355 nm with Nd:YAG Briliant laser. The system is capable of generating impulse coherent radiation in a wide range of wavelengths from 410 nm to 2600 nm. The basic repeating frequency (adjustable) is 10 Hz. The length of the output laser impulse is 6 ns to 8 ns according to the spectral area. The generated radiation includes the perspective spectral areas, considered for use in optical communications with fibre as well as atmospheric links. Using the UV module the spectral area can be extended to the UV wavelengths from 192 nm.
