Abstract

The invention discloses a regenerative amplifier provided with a multiplied resonator cavity. The regenerative amplifier comprises a tank body and optical modules, wherein an incident seed light inlet and an emitting amplification light outlet are formed in a right side plate of the tank body; the optical modules are arranged in the tank body and comprise an optical isolator, a regenerative resonance amplification cavity and a 45-degree totally-reflective mirror, wherein the optical isolator comprises a first polarizer, a Faraday rotator and a half wave plate; the regenerative resonance amplification cavity comprises a second polarizer, a first quarter wave plate, a first 0-degree totally-reflective mirror, a pulse option switch, a second 0-degree totally-reflective mirror, a third polarizer, a second quarter wave plate, a small-hole diaphragm, an LD pumping laser crystal module, a third quarter wave plate and a convex reflective lens. The regenerative amplifier has the advantages that regenerative amplification for weak ultrashort pulse seed light is achieved, great amplification times are achieved, the resonant cavity of the regenerative amplifier is designed, the multiplication of the cavity length is achieved, the geometric length of the resonant cavity is shortened, and the size of a laser device is reduced.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a regenerative amplifier with doubled resonant cavity. Background technique [0002] Ultra-short and ultra-intense pulse lasers have the advantages of narrow pulse width, high peak power, and tunable wavelength. , laser spectroscopy, photoelectric sampling technology, deep space exploration and other fields have a wide range of applications, and are of great significance to the study of ultra-high-speed phenomena and the regularity of the microcosm. [0003] In general, the repetition frequency of stable ultrashort pulses generated directly by mode-locking technology is 100 MHz, and the single pulse is in the order of nanojoules, and the power is low, which cannot directly meet the needs of applications. In order to obtain ultra-intense ultra-short laser pulse output, it is necessary to amplify the ultra-short pulse seed light. Generally, the ultrashort pulse seed light is ampli...
