Modelling And Development Of The Command And Simmer Circuits For The Power Supply Of Flash Lamp-Pumped Solid-State Lasers

In order to optically pump pulsed solid-state lasers like Nd: YAG laser, one needs a power supply that basically contains a trigger circuit, a main discharge circuit and a simmer circuit. These circuits must be synchronized by a command. In this communication we will present the synchronization circuit of the system. This circuit is a quartz oscillator known for its good frequency stability, followed by a frequency divider in order to have different repetition rates of the laser. We will also present the simmer circuit which was modelled using a voltage multiplier and a switch mode power supply. The same circuits were also simulated by using Pspice software, thus giving results in good agreement with those of modelling. Experimental proof of modelling has been obtained through the successful use of the command and simmer circuits to control the main discharge into a flash lamp operated at both 1 and 10 Hz frequencies.
