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.
Pantec Biosolutions AG presents a portable fractional ablative laser system based on a miniaturized diode pumped
Er:YAG laser. The system can operate at repetition rates up to 500 Hz and has an incorporated beam deflection unit. It is
smaller, lighter and cost efficient compared to systems based on lamp pumped Er:YAG lasers and incorporates a skin
layer detection to guarantee precise control of the microporation process. The pulse parameters enable a variety of
applications in dermatology and in general medicine, as demonstrated by first results on transdermal drug delivery of
FSH (follicle stimulating hormone).
A conductively cooled 970nm laser diode bar primarily designed for quasi continuous wave (qcw) pumping of
miniaturized solid state lasers is presented. The robust chip design and the highly efficient two side cooling setup of the
10x12x5mm<sup>3</sup> diode assembly allows output peak power levels as high as 600W at 500A drive current and 1% duty cycle.
The high performance laser diode was employed as pump for a miniaturized, conductively cooled, side pumped Er:YAG
laser system. The laser system, with an overall dimensions of 30x25x17mm3, generates 2.8W average power with M<sup>2</sup><5.
