Patent number: 6313433Abstract: A computer controlled laser material processing system has a plurality of laser sources the beams of which are selectively operable between two modes. In a first raster engraving mode the beams are separated and independently controllable in synchronism with the motions of a beam delivery system to form plural, parallel, spaced apart scan lines on the surface of the workpiece for affecting the surface at high speed. In a second vector cutting mode the beams are combined such that they are collinear and have a power approximately equal to the sum of the powers of each individual laser source for cutting the surface at high power.Type: GrantFiled: April 3, 2000Date of Patent: November 6, 2001Assignee: Universal Laser Systems, INCInventors: Yefim P.

Patent number: 6181719Abstract: A gas laser RF power supply has two RF oscillators operating at different frequencies, the first frequency to provide maximum RF voltage to the plasma tube prior to ignition, and the second frequency to provide optimum power for sustaining CW or pulse operation of the laser. The oscillator outputs are modulated to control power to the tube, the one in the form of RF pulses at the first frequency and at a power level below the laser emission threshold, and the other in CW or pulse form at the second frequency at a laser gas medium excitation level above the laser emission threshold. The first frequency is the resonance frequency of the tube prior to plasma ignition and the frequency of minimum average RF power required for a reliable ignition. The second frequency is the most efficient operating frequency for the plasma ignited and kept ionized by the pulses of the first frequency and provides maximum output laser power.Type: GrantFiled: November 24, 1998Date of Patent: January 30, 2001Assignee: Universal Laser Systems, Inc.Inventors: Yefim P. Sukhman, Mikhail E. Ryskin, David W. Schultz, George M. Mavroleon
