TOPTICA Photonics Inc.Request Info
Toptica Photonics Inc. has announced an ultrafast fiber laser with short pulse durations. The tunable ultracompressed pulse model of the FemtoFiber pro series provides a supercontinuum between 980 and 1400 nm, with >30-mW output power. The mode-locked fiber laser system features pulse durations <25 fs and is suitable for biophotonics, pump-probe experiments and femtosecond spectroscopy. The company says that it delivers high performance, ease of use, reliability and robustness. Based on saturable absorber mirror mode-locking technology and a core-pumped fiber amplifier, the master oscillator power amplifier platform is all fiber and based on polarization-maintaining fibers. The standard repetition rate is 80 MHz, with 40 MHz also available. Up to three fiber-coupled seed ports turn every FemtoFiber pro model into a complex laser system for multibeam experiments with optically synchronized laser pulses.

fiber laser
A laser in which the lasing medium is an optical fiber doped with low levels of rare-earth halides to make it capable of amplifying light. Output is tunable over a broad range and can be broadband. Laser diodes can be used for pumping because of the fiber laser's low threshold power, eliminating the need for cooling.
With respect to light radiation, the restriction of the vibrations of the magnetic or electric field vector to a single plane. In a beam of electromagnetic radiation, the polarization direction is the direction of the electric field vector (with no distinction between positive and negative as the field oscillates back and forth). The polarization vector is always in the plane at right angles to the beam direction. Near some given stationary point in space the polarization direction in the beam...
pulse duration
The lifetime of a laser pulse, generally defined as the time interval between the halfpower points on the leading and trailing edges of the pulse.
