Micromachining with copper lasers
Proceedings of LEOS'94, 2002The copper laser is the new laser in materials processing. It has shown great potential as a tool for high precision manufacturing. Commercial copper laser machining systems are now commercially available. Recent breakthroughs and on-going research in copper lasers will continue to scale the efficiency, output power and beam quality of these lasers.

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.

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 for Polymer Surface Topography Design
Journal of Visualized ExperimentsSoft magnetoactive elastomers (MAEs) are smart materials that respond to external magnetic fields by dynamically altering their mechanical properties. They are composed of magnetically responsive microparticles embedded within a soft polymer matrix, exhibiting an effective shear modulus of up to 100 kPa.
