Abstract

The invention relates to a method and a structure for realizing an iodine laser gain medium under high working pressure conditions, in particular to realize a high-pressure blade structure with lateral air intake and lateral outflow of high Mach number gas. The high-pressure gas enters the air intake chamber of the high-pressure blade through the upper side plate, and then flows into the buffer chamber through the air inlet hole, and then the gas flows through the throat of the blade from the buffer chamber, and the gas flows through the throat at the boundary of the expansion surface cavity Under the constraints of conditions, it begins to expand to form a high Mach number, low temperature, and low pressure gas flow, realizing a high working pressure iodine laser gain medium, and providing a gain medium for laser generation.

Description

technical field [0001] The invention relates to a realization method and structural design of a high working pressure iodine laser gain medium, specifically a method for realizing COIL with high working cavity pressure by using blades with high pressure and high Mach number and blades fed with iodine steam. Background technique [0002] The working pressure of the iodine laser gain medium in the oxygen iodine chemical laser (COIL) is generally 2-3 torr, which is beneficial to reduce the collision deactivation between gas molecules and improve the efficiency of the chemical laser. However, due to the low pressure of the working chamber, in order to ensure such a working condition, corresponding auxiliary equipment such as vacuum or ejector is required to discharge the residual gas of COIL into the atmosphere. And the volume of these auxiliary equipments is often quite large, and the electric energy that consumes is also relatively high. The lower the working pressure of the ...
