Cazadero – High Pulse Energy Femtosecond Fiber Laser (FLCPA)

The fiber laser based chirped pulse amplification system (FLCPA) generates high energy (up to 10 µJ) ultrashort (<0.7 ps) pulses at a repetition rate of 100s of KHz for either 1 or 1.5 µm wavelengths.

The fiber laser based chirped pulse amplification system (FLCPA) starts with a 25 MHz passively mode-locked seed fiber laser, sampled down to a pulse rate of 50 kHz or higher. The short pulse is time-stretched by frequency (chirped) for amplification through a high power fiber amplifier stage at lower peak intensity. Up to 10 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. The typical pulse width is 500 fs. The repetition rate can be adjusted up to 1500 kHz, depending on pulse energy, with average output power approaching 2 Watts. An RF synchronization output is provided as a trigger signal. This FLCPA is lightweight, compact, and maintenance free offering a reliable cost-effective alternative to Ti: Sapphire laser amplifiers.

* A sech² pulse shape (convolution factor of 0.65) is used to determine the pulse width for the second harmonic autocorrelation trace Due to our continuous improvement program, specifications are subject to change without notice
