Cazadero – High Pulse Energy Fiber Based Femtosecond Laser (FLCPA)

Cazadero Femtosecond Laser

The fiber laser based chirped pulse amplification system (FLCPA) generates high energy (up to 20 µJ) ultrafast laser pulses (<0.5 ps) at a repetition rate of 100s of KHz for either 1 or 1.5 µm wavelengths. The Cazadero ultrafast laser is also available in green (515 nm) and UV (343 nm) wavelengths.

The Cazadero FLCPA ultrafast laser starts with a 27 MHz passively mode-locked seed fiber laser, sampled down to a pulse rate of 120 kHz or higher. The ultrafast pulse is time-stretched by frequency (chirped) for amplification through a high power fiber amplifier stage at lower peak intensity. Up to 20 µJ of short pulse energy is delivered into free space. The wavelength can be selected in C-band (~1550 nm) or at 1 µm wavelengths. An RF synchronization output is provided as a trigger signal. This FLCPA is lightweight, compact, and maintenance free offering a rock-solid cost-effective alternative to solid state fs laser amplifiers.

* A sech2 pulse shape (convolution factor of 0.65) is used to determine the pulse width for the second harmonic autocorrelation trace
** The 515 nm and 343 nm are second harmonic and third harmonic of 1030 nm.

"Calmar's products have continued to perform well, even after several years, and are much lower maintenance than our other mode-locked lasers"
