Calmar Lasers has launched its new Carmel X-series femtosecond fiber lasers that provide high power, ultrashort pulses, and exceptional stability in the industry’s most compact package for OEM, scientific and industrial applications. The X-920 is the latest member of the product family with pulse widths < 120 fs and over 600 mW of output power at 920 nm, an ideal wavelength for multi-photon imaging of green fluorescent protein variants.
The Carmel X-series is a range of high power, air-cooled, 780 nm, 920 nm or 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, it provides the perfect source for a wide range of ultrafast laser applications, including bio-imaging, multi-photon 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 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 laser system 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 multi-photon microscopy applications, the Carmel provides an ideal ultrafast laser solution for optimum cellular tissue imaging with minimal scatter and reduced risk of photo damage. The compact laser head and associated armored fiber cable make for straight forward integration into existing microscopes with minimal delivery optics. The building block of the X-series is Calmar’s renowned ultrafast fiber laser seed platform, which utilizes the company’s proprietary passive mode-locking technology developed and perfected over a fifteen-year period. This ensures reliable startup, stable long term performance, and many hours of maintenance-free operation.
