A laser current selection method, system, device and readable storage medium

Abstract

The embodiment of the present application discloses a method, system, device, and computer-readable storage medium for current selection applied to lasers; in the embodiment of the present application, when the light-emitting enable signal is received, the first output corresponding to the light-emitting enable signal is obtained. Pre-current; when the light output command is detected, the drive current is obtained, and the drive current is used to drive the laser; when it is detected that the light output of the optical path module of the laser ends, the light output delay time parameter of the laser is obtained; at the current When the time is within the light emitting lag time parameter, a second pre-current is obtained, wherein the driving current is greater than the second pre-current and the first pre-current. It can eliminate the large-amplitude spikes in the optical path caused by continuous laser working in pulse mode, reduce the risk of fiber overload and burnout, and improve the stability of the laser.

Description

technical field [0001] The present application relates to the field of laser current loading, in particular to a current selection method, system, device and computer-readable storage medium. Background technique [0002] CW lasers have a stable working state, that is, a steady state. The number of particles at each energy level and the radiation field in the cavity in the CW laser have a stable distribution. The characteristic of its work is that the excitation of the working substance and the corresponding laser output can be continued in a continuous manner over a long period of time, including solid-state lasers excited by continuous light sources and gas lasers and semiconductor lasers that work in continuous electrical excitation. [0003] When the continuous laser works in the pulse mode, it will excite a large peak in the optical path, and the amplitude exceeds the set value by 20%, which will cause the laser fiber to be easily overloaded and burned, or make the sta...
