According to the laser emitter, components of the driving circuit and a laser arrayare integrated, the parasitic impedance of the driving circuit and a laser path is reduced, fewer technical steps are included, heave-current narrow-pulse laser emission under a temperature control condition can be provided, and an optical collimation function is provided.

Description

technical field [0001] The invention relates to the field of laser applications, and further relates to a laser emitting device. Background technique [0002] Semiconductor lasers have the advantages of good directionality, small size, light weight, long service life, and strong anti-interference ability, and are used in many fields. Pulsed laser is an application where the laser works in a pulsed state. The miniaturization, high peak optical power and output wavelength stability of pulsed laser emitting components are important directions for optimization. [0003] Under the original technical conditions, the power and waveform of laser pulses are affected by heat dissipation conditions and driving electric pulses. The thermal effect brought about by the increase of the output power of the semiconductor laser will lead to problems such as an increase in the temperature of the die and a decrease in the electro-optical conversion efficiency. Under the condition of high curr...
