Micromachining with Excimer Laser
CIRP Annals, 1998Abstract This paper deals with micromachining of different materials using a 100 W excimer laser at RTM laboratories. The first part of the works reports the results of optical simulations carried out on several layouts calculated using a sequential ray tracer in order to evaluate the aberrations and improve the performance of the optics and masks ...

Micromachining with copper lasers
SPIE Proceedings, 1997In recent years the copper laser has undergone extensive development and has emerged as a leading and unique laser for micromachining. The copper laser is a high average power (10 - 250 W), high pulse repetition rate (2 - 32 kHz), visible laser (511 nm and 578 nm) that produces high peak power (typically 200 kW), short pulses (30 ns) and very good beam

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 ...

Laser micromachining of efficient fiber microlenses
Applied Optics, 1990We present results of the use of a CO(2) waveguide laser for the reproducible fabrication of efficient microlenses on single-mode optical fibers. Short intense laser pulses are used both to melt microlens tips to specific radii and to micromachine microlenses by ablative removal of small (~1-mum(2)) areas of glass from the fiber surface.

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 ...
