Er:Glass can be diode pumped or lamp pumped. Lamp pumping is possible due to the broadband pump absorption mainly in the 800 nm region and the four-level characteristics. Er glass dental is a host medium with favorable properties, particularly for high-power lasers and Q-switched lasers emitting at 1064 nm.

A range of Er Glass 2940nm Lasers are used in analysis of elements in the periodic table. Though the Q switch Laser Er glass application by itself is fairly new with respect to conventional methods such as XRF or ICP, it has proven to be less time consuming and a cheaper option to test element concentrations. Light from the Laser Dental Erbium is captured by spectrometers and the characteristic spectra of each element can be identified, allowing ophthalmic glass laser concentrations of elements in the sample to be measured.

Er glass laser machine, laser peening typically uses high energy (10 to 40 Joule), 10 to 30 nanosecond pulse, flashed laser dental erbium systems to generate gigawatts of power on the surface of a part by focusing the laser beam down to a few millimeters in diameter. Medical fractional Er glass laser are used in manufacturing for engraving, etching, or marking a variety of metals and plastics, or for metal surface enhancement processes like laser peening.
