High Pulse Energy Fibre Laser Systems

http://www.fianium.com/products/highpulse.htm

FemtoPower1060-μJ are high power high pulse energy passively mode-locked fibre systems operating in the 1060 nm spectral range and delivering 15W of linearly polarised average power. A built-in pulse picker allows to change repetition rate stepwise from 20 MHz to 5 MHz and thus to increase pulse energy up to 4 μJ. The use of an optional pulse compressor allows a 10-fold reduction of pulsewidth and thus to achieve peak powers exceeding 1 MW from an air-cooled maintenance free compact fiber laser system.

Fianium leads consortium to receive £1.4M award / 09/2006

01.09.2006 : Fianium leads consortium to receive £1.4M award from Department of Trade and Industry on development of next generation fibre lasers. Southampton, United Kingdom (September 1, 2006): A consortium led by Fianium Ltd, a world leader in ultrafast fibre lasers, has received £1.4M ( $2.7M ) award from the UK Department of Trade and Industry to develop next generation fibre lasers for industrial and imaging applications. The DTI funded project ULTRAFAST is a collaborative project involving Fianium Ltd as lead partner, Lairdside Laser Engineering Centre, University of Liverpool as a partner responsible for materials processing characterisation, and the Centre for Photonics and Photonic Materials (CPPM) of the University of Bath who are developing novel fibre geometries for incorporation into Fianium’s products. LLLC will take delivery of a new picosecond fibre laser system from Fianium in January 2007 for materials processing characterisation trials as part of the ULTRAFAST project. The laser is a member of the FemtoPower series operating at a wavelength of 1064nm with a maximum pulse energy of 4μJ. The laser has a built-in pulse-picker which allows an end-user to step-wise change the laser repetition rate from 20 MHz to <1 MHz. CPPM will develop new types of photonic crystal fibres tailored for use within ultrafast fibre lasers to enable the delivery of femtosecond pulses with high peak powers. Dr John Clowes, Vice President of Research and Development at Fianium and project coordinator, is pleased with the potential outputs of the project: “ This award is a clear recognition of our achievements at the forefront of fibre laser technology. The collaboration with Lairdside and Bath University will be a great benefit in developing revolutionary new fibre lasers for materials processing and imaging applications. ” Dr Martin Sharp, manager of the Lairdside centre is encouraged by the success of ULTRAFAST “ I believe that it is important for Lairdside Laser Engineering Centre to foster a close relationship with laser companies such as Fianium, bringing our expertise in laser material processing to these projects and helping the company to exploit the laser source to its full extent. ” Dr. William Wadsworth, who leads the CPPM team, commented “ The ULTAFAST project gives us access to state of the art fibre lasers and allows us to carry out investigations in photonic materials using high energy and linearly polarised clean ultrashort optical pulses from a compact and user friendly fibre laser source. This will undoubtedly lead us to discovering exciting effects in photonic crystal fibres. ”

Fianium and the University of Bath Announce IP Assignment in Relation to Supercontinuum Generation/ Fianium 12/2008

17.12.2008 : Fianium and the University of Bath Announce IP Assignment in Relation to Supercontinuum Generation Southampton, United Kingdom (December 17, 2008) Ultrafast fibre laser manufacturers, Fianium, and the University of Bath have announced that rights in intellectual property generated by researchers at the Centre for Photonics and Photonic Materials (CPPM – University of Bath) has been acquired by Fianium for commercial exploitation. The Intellectual Property relates to the design of novel photonic crystal fibres and laser sources for generating enhanced-blue supercontinuum light sources. The discoveries made by Professor Jonathan Knight and his team at the CPPM in the field of supercontinuum generation have now enabled, for the first time, high brightness supercontinuum sources spanning from below 400nm to beyond 2.4um. “ Understanding how the supercontinuum works and what has historically limited the short-wavelength edge of the supercontinuum has been crucial in our latest developments ”, commented Prof Knight. “ Once we discovered the relationship between the short-wavelength barrier and the dispersion of the PCF, we were quickly able to design a fibre structure capable of producing such white supercontinuua with high blue spectral content. ” The responsibility for negotiating the exclusive transfer of the resulting IP on behalf of the University of Bath rested with the Bath Ventures team. Dr Malcolm Cross, Director of Bath Ventures, said: “ We are very pleased to have struck this deal with Fianium. They are a leading supplier of ultrafast supercontiuum fibre lasers, and as such, are ideally positioned to exploit this development. ” Anatoly Grudinin, CEO at Fianium., commented “ There is natural synergy between ultrafast fibre lasers and nonlinear photonic crystal fibres and over the past three years, Fianium and the CPPM have forged a strong and successful partnership. The CPPM has an unrivalled history in the field of photonic crystal fibre research, and we are extremely fortunate to be able to work so closely with Jonathan Knight and his team. ” Fianium has now incorporated the Bath fibre developments into the company’s SC400 product range delivering continuous spectra from below 400nm to beyond 2400nm. The additional 50nm of short wavelength spectral components within Fianium’s SC400 product range now meets the requirements of many customers by eliminating the blue-deficiency common to all existing commercial superocntinuum laser sources. The developments now mean that the supercontinuum fibre laser can be considered a truly white light laser.

white laser fianium 02/2008

Southampton, United Kingdom (February 22, 2008) Fianium have extended their unrivalled supercontinuum product portfolio with the release of the new SC400 and SC-PP laser sources, offering tunable pulse repetition rate from 100kHz to 40MHz and spectral content extending from below 400nm to beyond 2.5um. The SC400 is a world first for commercial supercontinuum systems, pushing the wavelength range of the laser to below 400nm while maintaining diffraction limited beam quality across the spectrum and delivering spectral brightness in the mW’s/nm range. The laser is based on proven fiber technology and operates at a fundamental repetition rate of 40 MHz. A built-in pulse picker allows the end-user to pre-set the repetition rate of the supecontiunuum radiation from 100kHz to 40 MHz. As a standard add-on unit, the supercontinuum lasers can be equipped with a multi-channel AOTF which provides up to 8 independently controlled wavelengths in the 400-2000 nm spectral range. “ The SC400 developments have been driven by customer needs to push the supercontinuum to ever shorter wavelengths, enabling replacement of conventional DPSS, diode and gas lasers in the visible from 405nm, ” commented John Clowes, VP of Research and Development at Fianium. “ The SC-PP adds an extra degree of flexibility to the supercontinuum technology, where tunable repetition rate enables measurement of varying lifetimes at any wavelength, something which previously required expensive modulated diode laser technology at very limited and discrete wavelengths. ”
