The Cazadero fiber laser chirped pulse amplification system (FLCPA) represents a unique product platform, offering pulse energies up to 3 µJ and pulse widths of less 500 fs at 1550 nm in a robust industrial package. It is the perfect source for two-photon integrated circuit testing, multiphoton microscopy studies, micro-machining and a host of other applications.
The system features a hands-off laser head and a rack mountable controller, which facilitate its incorporation into OEM designs and afford convenient access to high peak power optical pulses. A simple key switch interface provides for manual operation with full remote access through computer control. The system includes the capability of remote data logging, power monitoring and system diagnostics for OEM service support. The rugged, all fiber architecture is designed for 24/7 operation.
The building block of the Cazadero is Calmar’s renowned ultrafast fiber seed laser platform, which utilizes the proprietary Mendocino saturable absorber technology developed and perfected over a twenty-year period to deliver reproducible and reliable mode-locking at turn-on. The short pulse is stretched in time to reduce the pulse intensity through the high power amplifier stage and then recompressed to yield low pedestal, high energy output pulses. The pulse repetition rate and pulse energy are user selectable to ensure excellent signal-to-noise for data averaging applications. In addition, the output pulse width can be varied and optimized for every repetition rate to fine tune signal intensities or accommodate a range of processing parameters. An RF synchronization output is also provided as a trigger signal.
The Cazadero is a compact, flexible, fiber based femtosecond laser offering a reliable, cost-effective alternative to solid state laser amplifiers for biomedical, scientific, industrial, and research applications. The system is offered in two versions, the -01C is optimized for higher average power while the -02C is optimized for higher pulse energy.
