- Starting from theory,the stable effect of ARR in passively Q switched laser was analyzed.
- Satisfactory results are obtained in the patients with nevus of Ota treated with Q switched ruby laser.
- Purpose To find out the appropriate treatment interval in Q switched Alexandrite laser therapy of Nevus of Ota.
- Q switched laser, optical parameter oscillator, energy! power efficiency, frequency stability, message send and receive from COM port.
- In experiment, a Q switched ruby laser is used as light source, and a double exposure hologram of friction welding joint is obtained.
