What Are Solid-State Lasers?
Solid-state lasers are laser devices that use solid crystal or glass materials doped with rare-earth ions as the light-emitting medium. Typical materials include Nd:YAG, Nd:YVO4, and ruby crystals.
Simply put, the laser energy is generated by exciting the solid medium with a light source such as a laser diode or xenon lamp. After energy amplification inside the resonant cavity, the device outputs a stable, high-energy, concentrated laser beam.
Different from gas lasers and fiber lasers, solid-state lasers feature excellent beam quality, high peak power, and flexible pulse output, making them ideal for fine and high-precision work scenarios.
