With 30 µJ pulse energy, 370 fs pulse width, a M2<1.1, and tunable PRF and pulse width, the Cazadero offers a reliable, cost-effective alternative to solid state laser amplifiers for biomedical, scientific, and research applications.

Carmel - Compact Fiber Based Femtosecond Laser (CFL)

Carmel Femtosecond Laser

The Carmel fiber based femtosecond lasers (CFL series) offers high power, ultra-short pulses, and stable performance with a compact laser head for industrial, scientific, biomedical applications.

The Carmel is a high power, air cooled, fiber based femtosecond laser with an ultra compact laser head, about 100 times smaller than many Ti:Sapphire lasers with a similar output power levels. It is an easy to use, rugged, industrial laser system.

The Carmel’s operation is based upon the company’s proprietary is a passively mode-locked fiber laser technology, utilizing a saturable absorber, to ensure reliable startup and stable long term performance, with hands free operation. The Carmel offers user-friendly front panel control knobs for flexible system adjustment. The pulse width is less than 80 fs with a negligible pedestal. It has polarization-maintaining (PM) output and excellent beam quality, with an M2 < 1.2. An RF synchronization output is provided as a trigger signal.

The Carmel high power, fiber based femtosecond lasers enable you to focus on the job at hand, and not the laser tool being used.
