Paper Abstract

CO2 lasers as well as sealed CO2 lasers are well known and established in the industrial market. Due to the wavelength there is still a need for this type of lasers. New applications are demanding regarding pulse frequencies up to 100 kHz and more. Especially the printing and the automotive industry are markets which push innovations for these lasers. A novel design of combined rf amplifiers for high speed pulsing and gated pulsing for high pwm (pulse width modulation) in combination with suitable resonators is presented. The transient behavior of the rf signal during ignition brings todays semiconductors to their limits. Solutions for a reliable design are presented. The resulting super pulsed and gated pulsed CO2 laser beam is promising for state of the art applications. CLSM and SEM evaluation shows the advantages of pulsed laser operation with optimized laser resonators.
