Product Description

Product Overview

Laser crystal rods are optical components specially designed for laser generation and amplification, usually made of rare earth metal-doped crystal materials (such as neodymium-doped ytterbium garnet Nd:YAG, aluminum-doped garnet Yb:YAG, etc.). Their internal structure and doping composition enable them to effectively release lasers of a specific wavelength after being excited by pump light. Laser crystal rods are usually in the shape of rods, which are convenient for placement in the resonant cavity of the laser.

Laser crystal rods occupy a core position in laser equipment, and their importance is reflected in the following aspects:
