The invention provides a micro-channel 
semiconductor laser, which belongs to the field of 
semiconductor optoelectronic technology, and includes a base, a first micro-channel 
laser packaging module, a second micro-channel 
laser packaging module, a light output window and a sealed housing, and the base is provided with a water inlet and a water outlet.  And a circulating 
cooling channel; the first micro-channel laser 
package module includes a first micro-channel 
heat sink and a first laser 
chip packaged on the first micro-channel 
heat sink; the second micro-channel laser 
package module includes a second micro-channel 
heat sink and  The second laser 
chip is packaged on the second 
microchannel heat sink, the first laser 
chip and the second laser chip are arranged at an 
acute angle, and the 
light beam emitted by the first laser chip overlaps with the 
light beam emitted by the second laser chip.  In the micro-channel 
semiconductor laser provided by the present invention, two laser chips are arranged at an 
acute angle, and the emitted light beams intersect and superimpose to realize the superposition of 
optical power, improve the intensity and density of 
optical power, and meet the requirements of industrial 
processing.
