Micromachining with Copper Lasers
Proceedings of European Meeting on Lasers and Electro-Optics CLEOE-96, 1996The copper laser is a pulsed laser which emits intense (50 - 500 kW), short (20 - 60 ns) pulses at high pulse repetition frequencies (2 - 32 kHz). The laser radiation is in the visible with laser lines al 510.8 nm (green) and 578.2 nm (yellow). Average powers from commercial units range from 10 - 120 W whilst laboratory devices have reached 750 W ...

Femtosecond Laser Micromachining
2013Ultrashort laser pulses with durations in the femtosecond range up to a few picoseconds provide a unique method for the structuring of practically all materials with high precision and minimal thermal and mechanical influence of the surrounding. Due to the high intensities obtained in the focal volume even at moderate pulse energies not only surface ...

Precision Laser Micromachining
SPIE Proceedings, 1986Lasers continue to enter many exciting new fields that have been traditionally the domain of other equipment. Lately, lasers and their associated precision positioning equipment have replaced the more conventional methods used in the micromachining area because of better control, repeatability and precision.

Laser Micromachining of Thin Films
1998The laser-induced treatment is a physical way for changing material properties. Character and extent of the laser action are determined first of all by the radiation-flux density. At the same time it is possible to change the dimensions, shape, and electrical and optical parameters of the thin-film elements not only by direct removal of film material ...

Fundamentals of Laser Micromachining of Metals
1984Lasers as precise machining tools of high flexibility without wear out offer new possibilities for modification and processing of materials; there are already various applications such as drilling, cutting, welding, glazing, annealing and hardening. To understand and utilize laser microprocessing some of the physical processes involved are reported ...

Laser Micromachining of Ceramics
2011Laser surface processing of ceramics is an area of considerable technological importance for several structural, tribological, optical and electronic applications. The laser beam behaves as a heat source that induces a temperature rise on the surface and within the bulk of the material. Depending on laser parameters and material characteristics, lasers
