Abstract

The invention relates to a coaxial output multi-wavelength laser device. The laser device acquires multi-wavelength laser output with high repeated frequency, good beam quality, compact structure, andstable performance by using the slab laser technology and the optical parametric amplification technology, thereby guaranteeing a system in the whole pumping power range to work in a stable area; andthe output energy and stability of the laser is improved to a large extent. The high-energy and high-repeated frequency laser output is realized by using the orthogonal pumping technology, the wavelength locking and slab technology. The high-energy coaxial multi-wavelength laser output is obtained by using the pressurization Q-switching technology and pre-bias technology. The laser can be used asthe ideal laser source of the laser medicine, laser radar, photoelectric countermeasure and like fields due to the advantages of being multiple in output band, uniform in facula, and high in output energy; the laser device has the prominent advantages of being compact in structure, high in conversion efficiency and high in beam quality, and is extremely bright in application prospect.
