Abstract

The invention discloses Pulse deuterium fluoride (DF) laser device main engine structure with a molecular sieve adopted for processing and belongs to the technical field of superpower laser devices. An existing continuous wave laser device has the disadvantages of being large in structure, easy to explode and difficult to maintain in using process, and low in reliability. A pumping source is connected with a discharge electrode through an insulating plate. An upper left flow pass chamber is connected with the upper end of a discharging chamber. A first heat exchanger is respectively connected with the upper left flow pass chamber and an upper right flow pass chamber. An air outlet of a draught fan is connected with the upper right flow pass chamber through a flange. A wiring end of the draught fan is arranged outside an outer shell and is fixed on the shell body of the outer shell. A lower flow pass chamber is connected with the lower end of the discharging chamber. The lower flow pass chamber is connected with a second heat changer through a flange. The molecular sieve is connected on the second heat changer through a flange. The air which cooled by the second heat changer is exhausted to the hollow part of a chamber body through the molecular sieve. A resonant cavity is installed outside the outer shell. The pulse DF laser device main engine structure with the molecular sieve adopted for the processing achieves high average power laser output.

Description

Technical field [0001] The invention relates to the technical field of high-power lasers, in particular to a host structure design of a non-chain pulse DF chemical laser triggered by a discharge with a molecular sieve. Background technique [0002] The high-power DF laser, which has developed rapidly in recent years, has an output band of 3.5-4.1μm and a center wavelength of 3.8μm. Its operation mode is divided into two kinds of continuous wave and pulse. The current domestic research focuses on continuous wave mode. Continuous wave lasers have the advantages of high output power (up to megawatts), but they are large in structure, easy to explode, difficult to maintain, and low in reliability. The discharge-induced non-chain pulse DF laser avoids the shortcomings of continuous wave operation, and has the advantages of high average power and high peak power. In addition, the non-chain pulse DF laser has easy operation, no corrosion and explosion hazards, etc. advantage. [0003] ...
