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.  
CNI lasers have narrow pulse width, high peak power, and features of stable energy, easy operation, reliable performance and long life time.
The wavelengths of CNI lasers are available from ultraviolet to infrared range:
244nm     257nm     261nm     266nm     289nm   335nm     349nm    351nm     355nm     447nm     457nm    473nm     488nm     523.5nm         526.5nm     532nm     556nm    589nm     656.5nm     660nm     671nm    786nm    905nm   914nm     946nm     1030nm     1047nm        1053nm     1064nm     1313nm     1319nm     1342nm     1573nm     3800nm    3900-4500nm     4600nm     4800nm
