Fibre-based laser delivers picosecond
pulses
Coherent has launched the Talisker as the world's first fibre-based laser to offer high power, picosecond output in a rugged industrial package
With over 18watts of average power at a pulse repetition rate of 200kHz (pulsewidth < 15ps), this first fibre-based laser from Coherent will enable precision micromachining at high throughput rates with a negligible HAZ (heat affected zone) And, with a choice of infrared (1064nm), visible (532nm) or ultraviolet (355nm) output, Talisker 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.
For instance, its internal web server simplifies remote diagnostics and preventative maintenance.
Plus, the compact laser head measures only 17x39x77cm.
Talisker is a mode-locked laser with a unique architecture that combines the desirable characteristics of both fiber-based and free space lasers, while avoiding the inherent limitations of each.
Specifically, Talisker utilises a fibre-based oscillator that ensures industrial-grade stability, together with a bulk amplifier that boosts peak powers to higher than 10 megawatts.
In contrast, traditional fiber lasers are limited to peak powers that are orders of magnitude lower than this to avoid self-damage.
Talisker 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.
