A high power, diode-pumped Er:YAG laser platform is presented, which has been integrated into devices for soft as well as hard tissue applications. The highly efficient side pumping by qcw laser diodes allows easy power scalability and miniaturization proven by a portable fractional ablative laser system based on a 2 W laser. The high repetition rate of up to 1 kHz combined with low energy pulses generates high thermal impact and consequently strong skin rejuvenation. Furthermore a laser for hard tissue applications with up to 15 W average output power at repetition rates up to 2 kHz is presented. The good beam quality allows coupling to 200 µm fibers and the variable pulse duration of 1 to 200 µs ensures precise and fast treatments.
