Abstract

Recently, more and more people in laboratories and industrial companies have shown interest in using microchips laser. They wish to replace the pulsed lasers in their application because these sources are either old gas laser technology or require sophisticated and expensive designs. The passively Q-Switched microlasers are compact (1-2 mm), extremely simple, robust, very stable and use CW power supplies. Today, they are commercially available with 1W, 1x100 microns pump diode at different wavelength. The output energy at 1064 nm is up to 10 microJoules per pulse and the repetition rate up to 25 kHz. The gaussian ouput beam and the narrow pulsewidth (<1ns) produce high peak power up to 10kW. With such a source, people can mark on almost any surface.
