Abstract

Constituted from revolving frisbee type mechanical spark switch driven by step motor, electric copper converts output voltage from DC high voltage power source to ultra low frequency square wave pulse in high voltage. Output characteristics of pulse power source in high voltage are: (1) amplitude of output pulse as 2-100kV adjustable; (2) repetition rate range of output pulse 0.5-l00Hz; (3) width range of output pulse 0.5ms-1.9s; (4) current of output pulse larger than 300 microampere; (5) flat top drop of output pulse lower than 2%. The disclosed power source meets needs of polarizing nonlinear crystal material in each thickness, measuring optimal experimental parameters for periodic polarizing reversion for nonlinear crystal material, and batch production experiment for ferroelectric domain crystal in periodic reversed structure.

Description

Technical field

[0001] The invention relates to a power supply capable of outputting ultra-low repetition frequency and high-voltage rectangular wave pulses, which can meet the polarization requirements of nonlinear crystal materials with various thicknesses. Background technique

[0002] The development of modern optical technology has put forward newer and higher requirements for lasers. One of the most common and effective methods to broaden the laser output wavelength range is to use the frequency conversion technology of nonlinear crystals. Since nonlinear crystal materials must meet the requirement of phase matching when performing frequency conversion, people usually use the double refraction phase matching PMPhase Matching technology of anisotropic crystal birefringence characteristics and artificially prepare on nonlinear crystals. The QPM Quasi-phase-matching technology of the periodic structure is used to realize high-efficiency frequency conversion. Due to the ...
