532nm Laser (frequency-doubled Nd:YAG laser) is one of the most popular laser used in medicine treatment. Because of the high absorption rate of red substances to green laser, the blood vessels rich in hemoglobin can absorb most of the laser energy. Frequency-doubled Nd:YAG lasers (wavelength 532 nm) are used for pan-retinal photocoagulation in patients with diabetic retinopathy. In certain cases these lasers are also used to treat eye floaters.
Theotry
Gain medium - Nd YAG
The working medium of the laser here is doped with trivalent Neodymium ions in yttrium aluminum garnet crystal so that infrared laser with wavelength of 1064nm can be emitted.
AO-Q switch：TeO2
We use TeO2 crystal as AO-Q-switch so that we can control Q by changing radio-frequency signal provided to AO-Q-switch. Roughen side face of Yd:YAG crystal. Ground both sides of it into plane，Improving oscillation efficiency.
BBO Frequency Doubling
BBO was selected as frequency doubling crystal for Its good transmittance in 532nm and 1064nm and second-order nonlinear optical susceptibility. BBO change Yd:YAG laser into 532nm laser. harmonic separator is coated with 1064nm high transmittance films and 532nm high-reflective film strengthening the oscillation.
- Higher gasification result
- Minimal thermal damage
- Less bleeding
- Low lasing threshold
- High slope efficiency
- Large luminescence cross-section
- Linearly polarized emission and single-mode output
- partial irradiation hemostasis:
532nm laser has high gasification result and can rapid cut tissue, is less harmful to tissues around. Meanwhile because of the high absorption rate of red substances to green laser, the blood vessels rich in hemoglobin can absorb most of the laser energy. So 532nm laser is good at hemostasis.
