Toptica: Powerful femtosecond pulses at 1030 nm!

toptica FemtoFiber pro SCYb

TOPTICA expands their portfolio of ultrafast fiber-based laser systems.

TOPTICA's new FemtoFiber pro SCYb provides laser pulses with a center wavelength of 1030 nm and a duration below 100 fs. The turnkey system delivers typically 700 mW average output power making it the ideal laser source for specific applications in nonlinear microscopy or terahertz generation.

The new, all-fiber high-power laser system is based on a very stable, SAM mode-locked Er-doped oscillator operating at 1560 nm. The oscillator output is frequency-shifted towards 1030 nm using a nonlinear fiber. Yb-doped fiber amplifiers level up the power to typically 700 mW at the laser output. The system also includes a small grating compressor unit to achieve transform-limited output pulses of typically 90-100 fs, with more than 70 % 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 2 mm.

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 1030 nm 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 fiber lasers. With a modular design using erbium-doped and ytterbium-doped optical fibers, these lasers cover the spectral range from 488 - 2200 nm with pulses as short as 25 fs. All members of the family bring along the advantages of fiber-based laser technology: They are ultra-reliable, 100% hands-off and true turnkey systems.
