    The CO 2 lasers that were developed for these applications range in size from a few cubic centimeters that can easily be held in one hand, to many cubic meters that weigh several tons and occupy an entire building. The lasing time durations may range from less than 10 −12 sec to cw, with peak and average power levels greatly exceeding a terawatt and megawatt, :// KEYWORDS: Laser sources, Femtosecond phenomena, Mode locking, Physics, Fiber lasers, Profiling, Pulse shaping, Electro optics, Pulsed laser operation Read Abstract + The work presents for the first time generation of complex optical waveforms in a hybrid mode-locked fibre-semiconductor ://

      Even narrow bore CO2 lasers can be RF excited with the proper electrode configuration. Therefore, it might be possible to power your home-built CO2 laser using the output of a radio transmitter or RF power oscillator, or using the magnetron and its power supply from a microwave Conference on Lasers and Electro-Optics in Proceedings Conference on Lasers and Electro-Optics 19–22 June , Anaheim, California, United States papers in 67 sessions Change year: ?meetingid=18&yr=
