08 Jan 2015 ALPhANOV introduces a new triggered picosecond laser platform based on a fully fibered innovative design. This platform enabled the development of compact, robust and therefore reliable lasers, at a very affordable cost. The technology offers triggered picosecond pulses generally synchronized on TTL signal: this provides a more versatile operation than picosecond mode-locked lasers.
This platform is optimized to provide efficient frequency conversion and thus allows laser sources to operate at 1064, 532 or 355 nm, with pulse widths of less than 100 ps. Tests have also demonstrated operation with pulses of shorter duration down to femtosecond, still with a fully fibered deign and with a synchronized trigger.
The combination of high average power (above 50 W), high repetition rate (up to 2 MHz) and pulse energy of up to 50 μJ leads to a family of sources dedicated to numerous applications including: industrial machining for photovoltaic applications, selective ablation, cutting glass or LEDs; nonlinear optics via nonlinear crystals or fibers (supercontinuum generation, for instance).
