Abstract

The invention discloses a lateral pumping Nd:MgO:PPLN intermediate infrared laser and a biprism wavelength control method thereof. A total reflective mirror, a multi-period channel Nd:MgO:PPLN polarized crystal, an 813nm semiconductor pumping source, a first triangular prism, a second triangular prism, a small-hole diaphragm, a 45-degree mirror beam splitter, an acousto-optic Q switch and a 1.08 [mu]m fundamental frequency light total reflective mirror are sequentially placed in a straight cavity of the laser from right to left. And an intermediate infrared parametric light output mirror is placed in the zigzag cavity of the laser, so that light emitted from the 45-degree mirror beam splitter can reach the intermediate infrared parametric light output mirror.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a side-pumped Nd:MgO:PPLN mid-infrared laser and a double prism wavelength control method thereof. Background technique [0002] The 3-5μm mid-infrared band laser is in the main transmission window of the atmosphere, and has broad application prospects in military and civilian fields such as spectral detection, environmental monitoring, medical diagnosis, lidar, and photoelectric countermeasures. The optical parametric oscillator (QPM-OPO) based on quasi-phase matching technology has the outstanding advantages of high conversion efficiency and flexible tuning methods, and is one of the effective methods to obtain highly efficient and tunable mid-infrared lasers. Cutting-edge technologies such as differential absorption radar, THz light source, high-precision laser ranging system, and fine spectrum measurement put forward higher requirements for the stability of multi-wavelength mid-infrared...
