Description

Product Description                                                                                                     

1. Various output wavelength


2. Highly doped Er:YAG(50%): used as laser medium for 2940 nm wavelength. Due to the strong water and human body fluid absorption at this wavelength, Er:YAG laser has a wide dental and medical applications.


3. Low doped Er:YAG(<1%): applied to 1600nm ‘eye-safe’ laser.


4. Excellent optical and mechanical properties


5. An ideal laser crystal with wide pump band of 600~800nm.
