Abstract

Broadband and multi-wavelength laser is an emerging research direction with promising future applications. The optical parametric oscillator has the characteristic of wide tunable wavelength and the zinc sulfide polycrystal doped with Cr²⁺ ions have a wide absorption spectrum. Combining the advantages of both output and input, a unique cascade structure using optical parametric oscillator as pump source is constructed for Cr²⁺:ZnS laser resonator. The output advantages of the cascade laser are studied by analyzing the characteristics of the continuous wave and pulse laser output from the experimental device. The experimental system successfully outputs a laser with a wavelength of 2330 nm and an average power of over 510 mW. The experimental system realizes the laser output of four wavelengths over 2000 nm in the three spectral regions of near infrared, short wave infrared and medium wave infrared. The experimental results provide a new idea and reference for differential absorption measurement and multi-component material measurement in toxic gas molecular detection and optical measurement.
