PULSED LASER PUMPING SOURCE Russian patent published in 2024 - IPC H01S3/92 

FIELD: electricity.

SUBSTANCE: invention relates to the field of current pulse shaping equipment, in particular to devices for supply of pumping sources of pulsed solid-state lasers with the storage capacitor discharge. Pulse laser pumping source is made in the form of a closed circuit consisting of series-connected storage capacitor, a throttle, a pumping radiation source, a transistor switch with a control circuit and a current sensor, as well as a damping diode, together with a throttle and a pumping radiation source, which, when the switch is open, forms a second supply circuit of the pumping radiation source, wherein the pumping source comprises a zero bus. At that, in series with the current sensor, a second current sensor is introduced, by its first output connected to the first current sensor first output, the first current sensor is connected by its second output through the transistor switch to the low-voltage output of the storage capacitor, and the second output of the second current sensor is connected to the pumping radiation source. Connection point of current sensors is connected to zero bus and connected to output of damping diode, second output of which is connected to connection point of high-voltage output of storage capacitor with the throttle, as well as an analogue adder with direct and inverting inputs, connected to outputs of current sensors. A second transistor switch connected to the control circuit is introduced into the gap between the second input of the adder and the output of the second current sensor, and a Schmitt trigger is introduced between the output of the adder and the control input of the control circuit.

EFFECT: high efficiency of pumping, as well as high reliability of the device due to use of a low-voltage element base, which provides high accuracy of control and having high reliability, speed and minimum power consumption.
