Description

technical field [0001] The invention relates to a laser with multiple output wavelengths. Background technique [0002] The continuous development of laser technology makes it widely used in various fields. In the current practical application, no matter how much the output optical power is, a laser can only output a laser beam of a specific wavelength, and it is determined by the driving mode and principle of its driving circuit (mostly adopt constant current without temperature control) way) its output optical power and optical wavelength are poor in stability, and its application range is greatly limited. Most of the existing lasers that can output multiple wavelengths use the output mode of a beam splitter, but this output mode has a large transmission loss, which makes the transmission efficiency of the optical power output by the laser low. Contents of the invention [0003] In order to solve the technical problems of poor output optical power and optical wavelengt...
