Elliot Scientific is pleased to introduce Fibercryst, the only manufacturer of short pulse lasers and amplifiers utilising the innovative Single Crystal Fibre technology (SCF).
Originally developed from a series of University research programs, the SCF technology has been refined and commercialised by Fibercryst and patented jointly with the Institut d’Optique, and offers significant performance advantages over existing technologies. The products range from a full featured femtosecond micromachining laser, through a stand alone commercial amplifier, to individual amplifier modules:
- FEMTO is Fibercryst’s powerful industrial femtosecond pulse width laser offering output powers up to 25 W for high throughput, high quality micromachining. Based on Taranis technologies, pulse energies in excess of 80 µJ (@ 100 kHz) in pulse widths of less than 900 fs can be generated along with repetition rates selectable between 100 kHz and 2 MHz.
- Taranis Amplifier Systems are designed for a wide range of seed lasers providing either fibre coupled or free propagation mode inputs. The Taranis amplifier boosts a laser’s high average power, high peak power (up to 30 MW) and high pulse energy to free space.
- Taranis Laser Gain Modules are a unique solution to provide high peak power and high energy amplification using a simple and compact design. By using a single-crystal with a long length and a small diameter, short pulse amplification delivering a high intensity, linearly polarised laser light with superb beam quality and adjustable repetition rate can be achieved.
- Sub-nanosecond mJ laser: Fibercryst also offers an affordable, unique 1064 nm sub-ns laser system delivering more than 3 MW of peak power for use in research and test labs. Designed using MOPA architecture as a standalone unit combining a commercial 500 ps seed laser with the Fibercryst Taranis amplifier, it takes full advantage of the technology to provide a polarised beam, TEM00 output and 2 mJ of pulse energy for applications in LIBS, LIDAR & nonlinear optics; Supercontinuum, OPO, THz generation; and the biosciences.
Photodigm specialises in manufacturing high power single spatial and longitudinal mode laser diodes. By incorporating their proprietary DBR – Distributed Bragg Reflector – technology within a monolithic architecture, Photodigm delivers unequalled performance for researchers requiring excellent spectral purity and superior beam quality with high output powers, whilst ensuring long term reliability and stability. Typical high-resolution spectroscopy applications include:
- Atomic and Molecular Optical Physics
- Cold Atom Spectroscopy & Precision Instrumentation, for example:
- Advanced gravimeters
- Atomic clocks
- Raman Spectroscopy, Interferometry, Lidar and Metrology
With a narrow linewidth on the order of 1 MHz, and powers up to 300 mW, Photodigm DBR lasers are uniquely suited to numerous precision projects.

Firefly-IR’s broad mid-infrared wavelength coverage (~2.5 – 4.5 µm) allows users to probe the absorption features of many different molecules with a single device. Available in two standard power levels (Firefly-IR-250 and (Firefly-IR-60), the laser’s high average power and correspondingly high peak power (up to 200 W) afford high detection sensitivity and greater standoff distances. For more information, please contact us or download the Firefly-IR datasheet.
Nufern have introduced two Holmium doped fibres, increasing the operational wavelength of their standard range of active fibres to 2150 nm. The result of years of research and development, the fibres feature a double-clad design and the recently developed NuCOATTM coating technology, which affords greater durability and longer life.
The eye-safe Ho-doped standard fibres available through Elliot Scientific come in two geometrical configurations — a 25 µm core diameter with a 250 µm clad diameter, and a 40 µm core diameter with a 400 µm clad diameter. These fibres achieve 60% efficiency when resonantly pumped with a Thulium fibre laser. The optimal operating wavelength range for Ho-doped fibre is between 2000 and 2150 nm, making them an ideal choice for a variety of medical lasers as well as power scaling for a host of military laser applications such as LIDAR.
