Abstract

The invention relates to a computer-controlled adjusting method of the output wavelength of laser. A computer system (12) controls pump light to enter a first isolating device (7) automatically; pumplight transmitted by the first isolating device (7) enters a first total reflection mirror (1); and pump light transmitted by the first isolating device (7) enters a single-doped Ho:YVO4 crystal (2) and 2-micro laser is generated, and the generated laser enters a second total reflection mirror (3). After certain period of time, the computer system (12) controls second pump light to enter a secondisolating device (8) automatically; pump light transmitted by the second isolating device (8) enters the second total reflection mirror (3); laser enters an automatic light modulation assembly (4) andthe processed light enters an output coupling mirror (6) to form output light; and the output light is inputted into a detection device (11). A detection result is fed back to the computer system (12) in real time; and the angel of the automatic light modulation assembly is adjusted automatically based on the detection result, so that the performance of the output light is guaranteed to meet a preset condition.

Description

technical field [0001] The invention relates to a solid-state laser automatic adjustment technology, in particular to a computer-controlled laser output wavelength method. Background technique [0002] Lasers in the 2μm band are widely used, involving military affairs, infrared remote sensing, medical treatment, and optical communications. In particular, the mid-to-far infrared 3-12μm laser output can be achieved under the action of nonlinear conversion. The single-doped Ho solid-state laser using a 1.8-micron laser as a pump source is the best technical way to obtain a 2-micron laser at room temperature. At present, the single-end pumping method is basically used in single-doped Ho lasers, which reduces the uniformity of the laser crystal's absorption of pump light, leads to unbalanced heat distribution inside the crystal, and has a negative impact on the high-power operation of the laser. [0003] The existing light path adjustment technology is manual adjustment. Whether...
