Crylink

  An overview of Crylink's 532nm laser for Medical Application One of the most often utilized lasers in medicine is the 532nm laser (frequency-doubled Nd:YAG laser). Because red substances absorb green laser energy at a rapid rate, blood arteries rich in hemoglobin may absorb the majority of the laser energy. In patients with diabetic retinopathy, frequency-doubled Nd:YAG lasers ( wavelength532 nm ) are utilized for pan-retinal photocoagulation. These lasers are also used to cure eye floaters in some circumstances. Gain medium - Nd YAG In order to emit an infrared laser with a wavelength of 1064nm, the working medium of the laser is doped with trivalent Neodymium ions in a yttrium aluminum garnet crystal. AO-Q switch ： TeO 2        We employ a TeO2 crystal as an AO-Q-switch so that we may change the radio-frequency signal delivered to the AO-Q-switch to regulate Q. Roughen the Yd:YAG crystal's side face. Its oscillation efficiency is improved by grounding both sides

  1600nm Er YAG Laser For Optical Communication - Laser Crylink 1600nm laser is suitable for optical communication . 1600nm is located in the safe band of the human eye . And 1600nm is located in one of the atmospheric laser transmission windows, the transmission distance is farther, the corresponding distance and resolution and speed resolution are more accurate, and the corresponding photodetector parts have high detection sensitivity. Theory of 1600nm Er YAG laser Gain medium - Er：YAG The 4I11/2~4I13/2 and 4I13/2~4I15/2 transitions of the Er3+ ion produce laser radiation in two mid-infrared bands. The wavelength of the 4I11/2~4I13/2 transition is 2.7 μm~3 μm. 4I13/2~4I15/2 can emit at a wavelength of around 1.6 μm, which can meet the needs of space optical communication and other fields. E-O Q-switch：BBO Electro-optical Q-switching is to realize Q-modulation by using the electro-optic effect of the crystal, inserting a polarizer in the cavity, and using a polarizing plate to po
