Recent Achievements

  • A/Prof Stuart Jackson of the Mid-Infrared Sources Group in collaboration with colleagues at Laval University, Canada have recently had a paper published in the elite journal Optica. By cascading successive transitions of the erbium ion at 2.8 µm and 1.6 µm in a low-loss fluoride glass fiber laser cavity, the Mid-infrared Sources Group reports a record slope efficiency of 50% for emission at 2.8 µm with respect to the pump power at 980nm, thus exceeding the Stokes efficiency limit by 15%. This demonstration represents a significant advance for the field that paves the way for future demonstrations exceeding the 100 W power level at around 3 µm.

  • The Mid-Infrared Sources Group reported in the December 2017 issue of Optica an ultrafast mid-infrared fiber laser that overcomes many limitations involved with erbium-based systems by using holmium as the gain medium. Holmium allows the central emission wavelength to shift to nearly 2.9 μm and avoid the strong water vapor lines. This laser, which represents the longest wavelength mode-locked fiber laser, emits 7.6 nJ pulses at 180 fs duration, with a record peak power of 37 kW. At this power level, the laser surpasses many commercial free-space OPA systems and becomes attractive for laser surgery of human tissue, for industrial materials modification, and for driving broadband coherent supercontinuum in the mid-infrared.

  • Mid-Infrared Sources Group member and PhD student Mathew Majewski has won the Best Student Oral Paper Competition at the prestigious SPIE Fiber Lasers: Technology and Systems Conference that took place in San Francisco in Jan/Feb 2017. The conference is part of the LASE conference which is the biggest laser source conference in the world. The award of US $1000 was given Thursday 2 February 2017. http://spie.org/about-spie/press-room/spie-photonics-west-2017-news-and-photos/photonics-west-awards-and-honors-photo-gallery
  • A/Prof Stuart Jackson in collaboration with colleagues from the University of Adelaide have published work in Optics Letters reporting the demonstration of a fibre laser with the widest tuning range ever reported. The laser emitted light in the mid-infrared and was produced at a high efficiency. In future experiments it will be used for high discrimination gas sensing experiments.

  • PhD student Mathew Majewski and A/Prof Stuart Jackson have recently demonstrated a mid-infrared fibre laser with the highest efficiency yet reported. The fibre laser employed a novel lanthanide ion (dysprosium) and operated with a slope efficiency of 51%. The laser emission was measured between 3.04 um and 3.26 um.
