7-Wavelength Pulsed Laser System

We report on the laser system generating pulsed coherent radiation of seven wavelengths in short-wave infrared and visible ranges: 1572 nm, 1064 nm, 786 nm, 635 nm, 532 nm, 524 nm and 452 nm. It includes Nd:YAG laser (1064 nm), one LBO and five KTP crystals for frequency up-conversion and sum-frequency generation. Timing and energy parameters of all the spectral components are presented. Proposed system might be useful for high-speed multispectral imaging, wavelength-multiplexed holography and many other tasks.
