With over 18 watts of average power at a pulse repetition rate of 200 kHz (pulsewidth < 15 ps), the Talisker, a fiber-based laser from Coherent, enables precision micromachining at high throughput rates with a negligible heat affected zone (HAZ). And with a choice of infrared (1064 nm), visible (532 nm) or ultraviolet (355 nm) output, it can be used on virtually any material type, including metals, polymers, glass and semiconductors. Talisker is also configured to facilitate integration and for ease of use. Its internal web server simplifies remote diagnostics and preventative maintenance, and the compact laser head measures 17 cm x 39 cm x 77 cm.
Talisker is a mode-locked laser that combines characteristics of both fiber-based and free space lasers, while avoiding the inherent limitations of each. It uses a fiber-based oscillator for industrial-grade stability and a bulk amplifier that boosts peak powers to higher than 10 megawatts. The laser is intended for micromachining applications in the microelectronics, biomedical, semiconductor and solar device industries. Specific applications include drilling high quality holes in silicon and metals, direct write of flexible circuits/displays, scribing of flat panel displays/solar cells, micro milling, wafer dicing and metal surface treatments.
