Abstract

The invention discloses a wavelength-adjustable efficient high-power mid-infrared laser, which belongs to the technical field of lasers. According to the wavelength-adjustable mid-infrared laser, the conversion efficiency of a band-adjustable mid-infrared laser is improved. The wavelength-adjustable efficient high-power mid-infrared laser comprises a resonant cavity, a cascade amplification system, a collimating focusing system and an OPO, wherein the resonant cavity uses a ring-shaped full polarization-maintaining mixed dissipation resonant soliton lock mode to produce thalcium-doped fiber laser. A pumping source generates laser through a two-way pumping thulium-doped gain optical fiber. The laser oscillates back and forth in the resonant cavity and outputs nanosecond square wave pulse laser through an output coupler. The nanosecond square wave pulse laser is coupled into the OPO through the cascade amplification system and the collimating focusing system in order. Under the effect of the pulse laser and an OPO crystal, nanosecond pulse mid-infrared fiber laser is finally output through a filter and a dichroic mirror. The invention provides the mid-infrared laser.

Description

technical field [0001] The invention belongs to the technical field of lasers, and relates to a mid-infrared laser, in particular to a high-efficiency and high-power mid-infrared laser with adjustable wavelength. Background technique [0002] Today, wavelength-tunable mid-infrared lasers are mainly used in air pollution detection, remote sensing, spectral analysis, and military applications. The development of high-efficiency and high-power wavelength-tunable mid-infrared lasers has become a research hotspot. At present, it is most common to use an optical parametric oscillator (OPO, optical parametric oscillator) with a nanosecond pulsed fiber laser as a pump source to generate mid-infrared tunable laser light. Compared with solid-state lasers, fiber lasers have the characteristics of high power, high beam quality, and high conversion efficiency. Therefore, fiber lasers have been widely used as OPO pump sources. To achieve high-efficiency, high-power wavelength-tunable mi...
