Industrial ultrafast lasers enable precision microprocessing

In semiconductor microelectronics production, display fabrication, medical device manufacture and many other industries, there is an increasing trend towards higher precision processing of parts with smaller feature sizes and with reduced effect on surrounding material. Increasingly, ultrafast lasers with picosecond or femtosecond pulse widths are being used to accomplish these tasks. mehr

Miniaturized external cavity diode laser

Conventional diode lasers with external grating cavity are too sensitive and complex for many applications because of movable components. We are presenting a miniaturized diode laser with an external volume Bragg grating at 780 nm, with high output, narrow linewidth and almost diffraction-limited beam profile. This provides a stable and compact alternative to the distributed feedback laser. mehr

Flat-top beam: specialty fibers replace homogenizers

Flat-top beam profiles of diode lasers used in industrial applications are typically achieved through the use of shaping optics. Optical fibers with a rectangular core geometry offer an alternative. They actively participate in shaping the beam and replace, among other things, the expensive homogenizers. mehr
