Double-chip laser light source

The double-chip laser light source comprises a ceramic substrate, a chip bearing assembly is arranged at one end of the top of the ceramic substrate, and heat generated by chips can be rapidly conducted out; an optical fiber array is arranged at the other end of the top of the ceramic substrate, a thermistor is arranged at the top of the ceramic substrate and located on one side of the optical fiber array, the chip bearing assembly comprises a heat sink arranged at one end of the top of the ceramic substrate, and the heat sink is an aluminum nitride ceramic plate; a double-chip bar is arranged in the middle of the top of the heat sink, and an MPD monitoring detector is arranged at the top of the heat sink and located at one end of the double-chip bar. According to the invention, the number of parts in the pump laser module is greatly reduced, the assembly process difficulty of the pump laser is reduced, the part cost and the assembly working hours are reduced, and the product size design of clients can be red
