DUAL-WAVELENGTH LASER AND LASER THERAPEUTIC APPARATUS

摘要

Disclosed are a dual-wavelength laser and a laser therapeutic apparatus. The dual-wavelength laser therapeutic apparatus having a simple structure and high stability can switch to output a high-power 532 nm green laser and 1064 nm near-infrared laser by means of a movable reflecting lens (12) shifting between a first position and a second position. The 532 nm green laser is used for vaporizing and removing soft tissue, and the 1064 nm laser is used for cutting soft tissue and for hemostasis of large blood vessels and venous sinuses, thereby meeting surgical requirements and becoming a better solution for soft tissue surgery. A 532 nm laser resonator and a 1064 nm laser resonator share one pump, one Q switch and one back-cavity mirror. By means of a movable reflecting lens, a laser is divided into two lasers so as to switch to respectively output a 532 nm visible laser and a 1064 nm infrared laser.
