Alexandrite Laser Crystal

High thermal shock resistance: Alexandrite can withstand high temperatures and even achieve higher laser gain and efficiency under elevated temperatures. It possesses excellent thermo-mechanical and thermo-optical properties, with five times higher thermal shock resistance compared to Nd:YAG.

High damage threshold: The alexandrite rods feature a substantial damage threshold, enabling them to endure more than 1.5 million pulses.

Excellent for 755nm long-pulsed: Alexandrite laser crystals emit a spectrum of wavelengths, with the most efficient being around 755nm. This wavelength is well-absorbed by hair and melanin, making it ideal for aesthetic laser systems such as hair removal and tattoo removal.

Q-switch laser: The ability of Alexandrite Laser Crystals to emit light across a wide range of wavelengths allows for flexibility in Q-switching applications. Different materials may have optimal Q-switching parameters at different wavelengths, so the tunability of Alexandrite Laser Crystals is beneficial for finding the best conditions for a specific application.

Applications: Medical Field, Industrial Field, Remote Sensing and Radar Technology, Atmospheric Research, Ultrafast Laser Technology, Efficient Low-Threshold Lasers, etc.
