FSF Series 1030 nm Industry Grade Femtosecond Oscillators

This is not a usual laser. This is the superhero of laser oscillators. It has special superpowers that make it stand out from the crowd. Super-short yet ultra-fast. Small in size but very stable and robust. The earth may tremble but the laser will operate as usual. Same power, same pulse and no degradation over many years. Meet our Oscillator – the first SESAM-free and truly-all-fiber 1030 nm ultrafast laser.

This oscillator was specifically developed to be the rock-solid heart of the SFS series amplified system. It is built upon our truly-all-fibre technology, with no degradable components inside and no SESAM. The oscillator is equipped with a special self-starting solution ensuring the laser mode-locks every time. This feature together with the low size and power consumption makes the Oscillator perfect for OEM applications.opo, opa

FSF Series Optical Parametric Amplifiers

Our optical parameter amplifier is a device that precisely converts ultrafast pulses of one band (e.g. 1030 nm pulses coming from FSF series femto-second lasers) into a set of pulsed laser beams tunable in an extremely broad spectrum of wavelengths, ranging from 210nm up to 2600nm. All automated, all software-controlled.opo OPA

Growing number of ultrafast spectroscopy techniques has prompted the need for a robust and reliable, self-diagnostic device. The Optical Parametric Amplifier can be fully compatible with most femtosecond lasers and provides automated tuning across the basic tuning range.

Features:

The OPA is a versatile piece of equipment, due to its broad range of tuning and high conversion efficiency. When seeded with a reliable ultrafast laser such as our femto-second lasers, it may find use in many applications like pump probe spectroscopy, non-linear optics & neuroscience.

Application:

Non-Collinear Optical Parametric Amplifier

iNOPA™ is a white light continuum-seeded, non-collinear, optical parametric amplifier capable of generating extremely short pulses when pumped by the Model IMPULSETMYb-doped Fiber Oscillator/Amplifier. To generate short pulses the output beam of the Model IMPULSE laser is split into two beams inside the Model iNOPA enclosure. One beam is used to generate an extremely broad continuum seed beam which is then amplified by the second, higher intensity beam from IMPULSETMin a BBO crystal operated in a non-collinear arrangement. Non-collinear amplification preserves the very broad linewidth of the seed beam, which can then be compressed to a pulsewidth as short as 15 fs in a prism compressor. Non-collinear amplification is preferred since the resulting pulsewidth is dependent only on the bandwidth of the seed and not on the pulsewidth of the pump laser. In fact, conversion efficiency is improved by having a longer, rather than shorter, pump pulse because the there is more overlap in time between the two beams.
