The Laser is divided into continuous laser and pulse laser in operation. Pulsed Laser refers to a single laser pulse width less than 0.25 seconds, every interval of a certain time to work once the laser, it has a large output power, suitable for Laser Marking, cutting, ranging and so on. Common pulsed lasers include yttrium aluminum garnet (YAG) laser, ruby laser, neodymium glass laser, as well as nitrogen molecular laser, excimer laser and so on. Q-tuning and mode-locking are the two most commonly used techniques for obtaining pulsed lasers. The pulse width of pulse laser is usually less than ess than 0.25 seconds, which performs well in the field of laser marking, laser cutting and laser ranging.
CNI researches and develops Q-switched pulsed laser. The laser head comes with cooling and precise temperature control system, and power supply comes with overcurrent and overheating protection function.
