Abstract

The invention provides an electric-optically Q-switched switch driver, which comprises a DC high voltage source, and is characterized in that: the electric-optically Q-switched switch driver also comprises first and second current limit resistors, first and second switch circuits and a trigger circuit; the DC high voltage source, the first current limit resistor, the first switch circuit and a trigger signal form a voltage-decreased circuit; and the DC high voltage source, the second current limit resistor, the second switch circuit and a trigger signal form another voltage-decreased circuit. When used as a voltage-increased electric-optically Q-switched driver, the electric-optically Q-switched switch driver can chop laser pulses and compress laser pulse width; and when used as two voltage-decreased electric-optically Q-switched drivers, the electric-optically Q-switched switch driver is applied to a dual electric-optically Q-switched laser to double the repetition frequency.

Description

technical field [0001] The invention belongs to laser application technology, and in particular relates to a novel electro-optic Q-switching drive power supply. Background technique [0002] Electro-optic Q-switching technology is a technology that uses the electro-optic effect of crystals to realize Q-value mutations, compresses laser energy into extremely narrow pulses and emits them, so that the peak power of laser output can be increased by several orders of magnitude. The working mode of the electro-optical Q-switching switch is usually divided into two types: back pressure type and pressure type. The working principle of electro-optic Q-switching switch devoltage is as follows: When the potential difference between the two poles of the electro-optic crystal is high voltage, the loss in the laser resonator is very large, the Q value is small, and laser oscillation cannot be formed, and there is no laser output, which is called the electro-optic crystal. When the potent...
