We have developed a picosecond 755 nm alexandrite laser system. To generate picosecond laser pulses, we used self-injection techniques including Q-switch and cavity dump without mode-locking method. We have achieved through a comprehensive combination of complex optical technique, thermodynamic design, high power design, high-speed driver, and precise control technique. The uniform energy of the beam profile allows a safe and effective treatment outcome to be predicted.
