Abstract
The modification of a power supply circuit used for pumping metal vapor lasers is analyzed. The results of OrCAD simulation of the processes that occur in the power supply are presented. The effect of the capacitance ratio on the charging process of a storage capacitor is described. The mode which provides more time for the recovery of the thyratron is discussed. The results of the development of the small-size high pulse repetition frequency laser with up to 3 W average output power are presented.
Highlights
The range of applications of metal vapor lasers is wide, including a number of medical ones
The aim of this work is to upgrade the power supply and study its operation modes using OrCAD models. Another aim is to develop a compact high frequency CuBr laser with the pumping circuit based on a TGI1-270/12 thyratron
To sum it up, the results of OrCAD simulation of the processes that occur in the power supply based on an H-bridge inverter are presented
Summary
The range of applications of metal vapor lasers is wide, including a number of medical ones. Laser pumping circuits based on the direct discharge of the storage capacitor, are described in [4,5,6] The disadvantage of these circuits is that a thyratron recovers its electrical resistance when the anode voltage is applied since the storage capacitor begins to charge immediately after its discharge on the GDT. This makes it impossible to increase the PRF of these devices. The aim of this work is to upgrade the power supply and study its operation modes using OrCAD models Another aim is to develop a compact high frequency CuBr laser with the pumping circuit based on a TGI1-270/12 thyratron.
