Femtofiber pro SCYb

Toptica's FemtoFiber pro SCYb provides 700mW at 1,030nm with less than 100fs pulse duration.

Toptica’s new Femtofiber pro SCYb provides laser pulses with a centre wavelength of 1,030nm and a duration below 100fs. The turnkey system delivers typically 700mW average output power making it the ideal laser source for specific applications in nonlinear microscopy or terahertz generation.

The new, all-fibre high-power laser system is based on a very stable, SAM mode-locked Er-doped oscillator operating at 1,560nm. The oscillator output is frequency-shifted towards 1,030nm using a nonlinear fibre. Yb-doped fibre amplifiers level up the power to typically 700mW at the laser output. The system also includes a small grating compressor unit to achieve transform-limited output pulses of typically 90-100fs, with more than 70 per cent of the total power in the main peak. It operates at a repetition rate of 80 MHz and provides a TEM00-beam shape with M2 < 1.2 and a beam diameter of 2mm.

The Femtofiber pro SCYb is a very cost-effective and compact laser system that provides high power at the given wavelength with an excellent beam quality. It can be easily integrated in existing beam paths and extend the power level at the important wavelength of 1,030nm while the shortest pulse duration is maintained via built-in dispersion compensation. It is the perfect solution for applications in nonlinear microscopy, like effective two-photon excitation of fluorescent proteins and SHG based contrast mechanisms. In addition, the Femtofiber pro SCYb is ideally suited for the generation of pulsed THz radiation.  

All of this is integrated into an ultra-compact system with a footprint of less than Letter/A4 format, and can be controlled easily via Ethernet, USB or RS-232. A simple browser-based GUI enables user-friendly access to all laser parameters. Alternatively, LabVIEWTM routines are available that guarantee a straightforward integration of the laser into existing systems.  

 The Femtofiber pro family is TOPTICA’s second generation of pulsed fibre lasers. With a modular design using erbium-doped and ytterbiumdoped optical fibres, these lasers cover the spectral range from 488 – 2,200nm with pulses as short as 25fs. All members of the family bring along the advantages of fibre-based laser technology: They are ultrareliable, 100 per cent hands-off and true turnkey systems.
