Q-Switch

Q-Switch lasers use very short but high-energy pulses, typically only a nano-second long. They can produce different wavelengths of light, including 1064 nm and 532 nm. Q-switch laser applications include material processing (laser cutting, marking, drilling, and patterning), dermatology, tatto removal, fluorescence spectroscopy, pumping devices for nonlinear frequency conversion, laser rangefinders, and LIDAR for 3-dimensional imaging. 

High pulse energies and peak powers pose serious laser safety issues for the eyes, even for lasers with low average output power. A single direct shot into an eye could cause severe retinal injury, so proper laser safety eyewear is critical. 

Browse our LaserShield® filters using the Wavelength Selection Tool in the left side navigation. If you need to calculate the OD for your required level of protection, please use our OD Calculator tool or call us at 800-521-9746 to assist you with choosing the right filter for your application.
