[0002] Generally, the light condensing cavity is composed of a working medium, a pumping light device and a temperature control system, etc. In the working process, the pumping light will produce a large amount of heat when irradiating the working medium, which will directly affect the performance of the working medium and thus affect the output parameters of the laser.

[0003] In the prior art, the temperature of the light condensing cavity is usually controlled by using cooling liquid to ensure the constant temperature state of the light condensing cavity. When the cooling liquid is connected to one end of the light condensing cavity, the cooling liquid will be divided into two paths, one of which is used for heat dissipation of the working medium and the other of which is used for heat dissipation of the pumping side wall.

The liquid inlet assembly 1 comprises a sealed shell 11 and n automatic adjusting structures 12. The outer surface of the sealed shell 11 is provided with a total liquid inlet hole 111, a first liquid outlet hole 112 and n second liquid outlet holes 113. The n automatic adjusting structures 12 are arranged in the sealed shell 11. The automatic adjusting structure 12 comprises a memory spring 121 and a liquid blocking piece 122. The memory spring 121 can be elongated or shortened with the change of temperature, and the first end of the memory spring 121 is in close contact with the first end of the liquid blocking piece 122. During the elongation process, the liquid blocking piece 122 can be pushed to move in the first direction, and the second end of the liquid blocking piece 122 is adapted to the shape of the second liquid outlet hole 113. During the movement of the liquid blocking piece 122 in the first direction, the second end of the liquid blocking piece 122 can gradually block the second liquid outlet hole 113.

The top end of the sealed tube 21 is in close contact with the first liquid outlet hole 112, and the top end of the heat conducting piece 22 penetrates through the first liquid outlet hole 112 and enters the inside of the liquid inlet assembly 1, and is adjacent to the second end of the n memory springs 121 respectively. The pumping assembly 3 comprises n pumping side walls. The first surface area and the inside of the pumping side wall are porous structures, and the first surface area of the pumping side wall is in close contact with the second liquid outlet hole 113.

[0075] As can be seen from the above, the light condensation cavity can adjust the flow of the cooling liquid flowing to the pumping side wall based on the temperature, thereby adjusting the flow of the cooling liquid flowing to the sealed tube 21, adjusting the temperature of the working medium, and improving the stability of the temperature in the light condensation cavity.

That is, the second force corresponding to the first force described in the specification does not mean that the second force and the first force are exactly equal in size and opposite in direction, but under the influence of friction, the second force and the first force, the force balance between each part is zero and no longer deformed.

[0120] ​In the 1990s, it was relatively easy to distinguish whether an improvement in a technology was a hardware improvement (e.g., an improvement in the circuit structure of a diode, transistor, switch, etc.) or a software improvement (an improvement in a method flow). However, as technology has evolved, many improvements in method flows today can be considered as direct improvements in hardware circuit structures. Designers almost always obtain the corresponding hardware circuit structures by programming the improved method flows into hardware circuits. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using hardware entity modules. For example, a programmable logic device (PLD) (e.g., a field programmable gate array (FPGA)) is an integrated circuit whose logic function is determined by user programming of the device. A digital system is "integrated" on a PLD by the designer programming the PLD, rather than by ordering a custom integrated circuit chip from a chip fabricator. Moreover, instead of manually fabricating an integrated circuit chip, this programming is now mostly implemented using "logic compiler" software, which is similar to software compilers used in program development, and the original code to be compiled is written in a specific programming language, which is called a hardware description language (HDL), and there are many such languages, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., and the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should be aware that, as long as the method flow is logically programmed and programmed into an integrated circuit using the above-mentioned hardware description languages, a hardware circuit that implements the logical method flow can be easily obtained.

[0121] The controller can be implemented in any suitable way, for example, the controller can take the form of a microprocessor or processor and a computer readable medium storing computer readable program code, such as software or firmware, executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller and an embedded microcontroller, examples of which include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicone Labs C8051F320, the memory controller can also be implemented as part of the control logic of the memory.
