Carmel X - Compact High Power Femtosecond Fiber Laser (CFL)

Multiphoton Microscopy Femtosecond Laser

The Carmel X-series (CFL) is a range of high power, air-cooled, 780 nm and 1550 nm fiber-based femtosecond lasers with output powers from 0.2 to greater than 2.0 W. With pulse widths of less than 90 fs in a small user-friendly package, the X-series provides the perfect source for a wide range of ultrafast laser applications, including bio-imaging, multiphoton microscopy, optical metrology, 3D-microprinting, terahertz imaging and ophthalmology.

The system features a rack mountable controller with a robust armored cable interface to the compact laser head, which facilitates its incorporation into OEM designs. It is over 100 times smaller than many Ti:sapphire lasers with a similar output power level. A simple key switch interface provides for manual operation with full remote access through computer control. The X-series includes the capability of remote data logging, power monitoring, system diagnostics, and automated adjustments for prolonged lifetime and OEM service support.

1 A sech2 pulse shape (deconvolution factor of 0.65) is used to determine the pulse width from the second harmonic autocorrelation trace.

2 The absolute pulse energy will depend on the version and specified repetition rate.

3 For the 780, 1 W version, the repetition rate is 80 MHz, otherwise the repetition rate needs to be specified at the time of purchase.

(Due to our continuous improvement program, specifications are subject to change without notice).

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