Three-Wavelength YAG: Nd3+ Laser System for Lidar Sounding of Marine Areas

The article presents the results of the UV, visible, and IR spectral range measurements of temporary parameters of single radiation pulses of a modernised RGB laser with an intracavity parametric light oscillator. It is proposed to transform the modernised RGB laser into a three-wave multifunctional laser system generating shorter and more powerful 532 and 452 nm single radiation pulses with quick switching between them. The laser system is designed for operation as part of a marine aviation radio metrical lidar and has an additional channel of safe for sight radiation with wavelength of 1572 nm to control flight altitude above sea level.
