Outstanding beam quality (M2 < 1.2)
Exceptional beam pointing stability
All air-cooled, no chiller required
Optional 1550 nm output
Full computer control and data logging capability
Remote system diagnostics
Expected lifetime > 10,000 hours

The Carmel X-series is a range of high power, air-cooled, 780 nm (and optional 1550 nm), fiber-based femtosecond lasers
with output powers from 0.2 to greater than 1.0 W. With pulse widths of less than 90 fs in a small user-friendly package,
the Carmel 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, whichfacilitates 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 adjustment of the second harmonic crystal for prolonged lifetime and OEM service support. The rugged design supports 24/7
operation with an expected lifetime of > 10,000 hours.
The Carmel can be configured for dual wavelength output to enable alternating between 780 and 1550 nm outputs. The
repetition rate can be specified from 10 to 80 MHz with a clean pulse width of < 90 fs, and outstanding beam quality (M2 <1.2). Excellent long term pulse-to-pulse stability (<1% rms) over a wide operating temperature range (17-30°C) ensures
superior results for both tissue imaging and ablation in biomedical applications. An RF synchronization output is also provided as a trigger signal.
For multiphoton microscopy applications, the Carmel provides an ideal ultrafast laser solution for optimum cellular tissue
imaging with minimal scatter and reduced risk of photodamage. The compact laser head and associated armored fiber cablemake for straight forward integration into existing microscopes with minimal delivery optics.

1For the -04 and -05 models, the repetition rate needs to be specified at the time of purchase. For other repetition rates, please contact
sales@calmarlaser.com.
21550 nm output is also available from a separate port (switchable with the 780 nm output). This option should be specified at the timeof purchase, please contact sales@calmarlaser.com for more details.
