ERB15

This Er:YAG laser, which is Q-switched using the FTIR modulator, is unique in its form.
It generates 60 ns short pulses at a pulse energy of 15 mJ.
Laser systems that generate radiation at 2940 nm are of particular interest for medical applications, as this wavelength has a 10,000 times higher absorption in water than radiation at 1064 nm.

With its high peak pulse power, the ERB15 is an ideal tool for a wide range of medical applications.
Compared to all other lasers, the Er:YAG laser with a wavelength of 3 µm has the largest absorption coefficient for water and the lowest penetration depth.
A frequency-doubled Nd:YAG laser, for example, requires 40 million times more pulse energy than an Er:YAG laser to cause the same temperature increase in water with the same cross-sectional area.
