ERB15 laser system

This Er:YAG laser, Q-switched by means of 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 10,000 times higher absorption in water than radiation at 1064 nm.

With its high peak pulse power, the ERB15 thus becomes an ideal tool for a wide range of medical applications. Compared to all other lasers, the Er:YAG laser with 3 µm wavelength has the highest absorption coefficient and the lowest penetration depth for water. A frequency-doubled Nd:YAG laser, for example, needs 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.
