Trends in laser micromachining
SPIE Proceedings, 2016Laser Micromachining is well established in industry. Depending on the application lasers with pulse length from μseconds to femtoseconds and wavelengths from 1064nm and its harmonics up to 5μm or 10.6μm are used. Ultrafast laser machining using pulses with pico or femtosecond duration pulses is gaining traction, as it offers very precise processing of

Picosecond lasers in micromachining
ICALEO 2003: 22nd International Congress on Laser Materials Processing and Laser Microfabrication, 2003Recent improvements to mode-locked lasers with picosecond pulse duration have fueled an increased interest for industrial applications, especially micromachining. Short pulses offer advantages for ablation of various materials. Reduced thermal load, low ablation threshold and other advantages of shorter pulses need to be tested for real application.

Laser applications for micromachining
AIP Conference Proceedings, 1996Laser assisted silicon etching was developed for packaged microsensors. Laser assisted Cr CVD was applied for selective metallization on nonplaner surfaces. High rate laser CVD using low temperature condensation method was developed for micro assembly and projection patterning.

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 ...

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 ...

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.
