Problems solved by technology

However, a fixed hardware design can only achieve a certain laser pulse width output
Since the solid-state laser needs to work at a specific pump intensity to ensure that the laser is under a specific thermal effect that can work stably, in actual work, it is not realistic to try to achieve a controllable change in the laser pulse width by changing the pump intensity. , so that a specific design and manufacture of solid-state lasers can only guarantee a specific laser pulse width corresponding to a specific pulse repetition frequency

[0012] specific implementation plan

[0013] figure 1 A schematic diagram of a typical side-pumped solid-state laser is shown. Among them, 01 is a laser total reflection mirror, 02 is a laser output mirror, 04 is a solid-state laser working substance, 05 is an acousto-optic Q switch, and 06 is an output laser beam. 03 is a pump laser diode or a laser diode group, including possible optical beam shaping elements (not shown in the figure). The output pump beam (not shown in the figure) is coupled into the side of the laser working material. 010 is the power supply of the laser, its output 011 is used to drive the pumping diode 03, and the input 013 provides the driving electrical signal for the acousto-optic Q switch 05.

[0014] Since the pump light is coupled to the side of the laser working material directly or after being focused, the pump intensity in the pumped area is correspondingly low, which is different from that of laser TEM. 00 The area overlap of the working mo...

Abstract

The invention relates to a pulse width adjustable laser. A diode-pumped acousto-optic Q-switched solid-state laser can be used for performing terminal pumping or side pumping on a solid-state laser working material, or performing proper terminal pumping and side pumping on the solid-state laser working material in a properly-combined manner; it can be ensured that the laser works under substantially the same thermal effect; and therefore, the pulse width controllability of laser pulses can be realized.

Description

technical field [0001] The laser diode-pumped acousto-optic Q-switched solid-state laser can realize controllable laser pulse width. Background technique [0002] Solid-state lasers pumped by laser diodes are widely used in laser processing, medical treatment and military affairs. [0003] Typical diode-pumped solid-state lasers use two typical pumping methods, side pumping and end pumping. [0004] When the diode side-pumps the working substance of the solid-state laser, the diode slab is usually directly approached to the side of the working substance of the solid-state laser for direct pumping, or only a simple beam shaping optical element is used to properly adjust the output light of the diode. Focus on shaping. The advantage is that the pumped area of ​​the solid-state laser working material is large, and it is easy to achieve high power output of the solid-state laser by increasing the number of pump diodes. But another feature is that the pump light has a large di...
