Abstract
The invention discloses a large-power 1064 nm near-infrared laser based on a wattle structure. The large-power 1064 nm near-infrared laser based on the wattle structure is characterized in that the large-power 1064 nm near-infrared laser based on the wattle structure comprises a laser crystal, optical lenses placed on both sides of the laser crystal and a semiconductor laser pumping module, a laser resonant cavity forming pump lights into 1064 nm lasers with high beam quality and a modulating component modulating the lasers, wherein the laser crystal is a wafer with the wattle structure, an optical direction of the pump lights is in the wafer, a M-shaped light path is formed by the lasers in the laser. The large-power 1064 nm near-infrared laser based on the wattle structure has the advantages that the first-order hot focus, the stress birefringence and the depolarization effect can be lightened even eliminated through the reasonable M-shaped light path designed and the curvature radius of the cylindrical mirror chosen appropriately, thus the simple wattle laser structure is used so as to obtain better light bean quality and higher output power. A diaphragm is arranged inside the laser resonant cavity and can further improve the light beam quality.
