Toptica FemtoFErb 780: turnkey pulses with sub-100 fsec

FemtoFErb 780 01

FemtoFErb 780 – compact all-fiber laser with < 100 fs pulse width and > 50 mW at 780 nm.  

Most compact and cost effective ultrafast fiber laser for terahertz and biophotonics

TOPTICA’s new FemtoFErb 780, a turnkey laser system, delivers 50 mW average power at 780 nm center wavelength with a pulse duration of less than 100 fs at a repetition rate of 100 MHz. Based on polarization-maintaining Erbium-doped fibers and saturable absorber mirror (SAM) mode-locking technology, the all-fiber system features a compact SHG unit and comes with a free-beam output. Combining optics with the entire control electronics on a footprint of only 202 x 122 x 69 mm3 makes the FemtoFErb 780 the most compact fs-fiber laser commercially available. A perfect match for the requirements of time-domain terahertz, the FemtoFErb 780 also provides an ideal seeding source for Ti:Sapphire systems. In addition, this cost-effective replacement for bulky solid-state lasers suits various applications in biophotonics, ranging from SHG microscopy to multi-photon excitation.


Fiber technology ensures a very compact design as well as highest robustness against vibrations and mechanical shocks. Telecom-qualified components guarantee round-the-clock reliability and a long lifetime. And finally, its passive SAM device ensures reliable self-starting and mode-locking.

A plug&play system for both OEM integrators and single-unit customers, the FemtoFErb provides an electrical interface for remote control and only requires a 12 V supply to drive all internal electronics. An optional SwitchBox provides all switches, supplies and status lines needed to run the laser as a stand-alone system without integration environment.
