Abstract

The invention discloses a diode-pumped quasi-continuous high-power laser with a red wavelength and a green wavelength. It dopes the Nd3 + laser crystals as the working material, and adopts the nonlinear optical crystal frequency technology and acousto-optic technology, and converts the laser in the band of 1.3 micron to 1.0 micron into the dual wavelength pre-continuous laser of green and red through double-frequency method. The invention can achieves a laser output of dual-wavelength of red and green at the same time, or an alternating laser output of dual-wavelength of red and green through the chopper in the resonator.

Description

technical field [0001] The invention relates to a laser, in particular to an LD side-pumped quasi-continuous high-power red and green dual-wavelength laser. Background technique [0002] Since the birth of the world's first ruby ​​laser in 1960, various lasers and laser technologies have developed extremely rapidly. Among them, the development of dual-wavelength lasers has attracted much attention. It overcomes the defect of lasers outputting a single wavelength, and has broad market and application prospects in many fields, and has become a hot research topic at home and abroad. As the second of the three primary colors, the red and green dual-wavelength lasers occupy an important position in laser medicine, laser color display, laser full-color film, atmospheric monitoring and scientific experiments due to their unique advantages in the visible light range. Research value and application value, there are related reports at home and abroad that use nonlinear optical crysta...
