Photon Science Institute
The Alan Turing Building

Located in the Alan Turing Building, the Photon Science Institute comprises a wide range of laser systems, which together provide a unique array of sources. Our aim is to assemble a diverse range of wavelengths with the narrowest linewidths, highest powers, and shortest pulses; so researchers can pursue a variety of activities quickly, facilitating interdisciplinary research and external collaborations.

We have many sophisticated experimental systems, and have invested in key basic facilities which allow immediate exploitation of our laser sources. These include UV-VIS-NIR absorption and fluorescence spectroscopy, high spatial resolution fluorescence spectroscopy, and triple Raman/photoluminescence spectroscopy.

In addition, we have an extensive array of diagnostic equipment; including fast oscilloscopes, detectors, power and energy meters, spectrometers, and fibre delivery systems.

See the Photon Science Institute website for more information.

Continuous wave (CW), narrow linewidth tunable sources

Intended for the highest resolution spectroscopic work, these systems are based on titanium sapphire and dye laser ring oscillators, and with frequency doubling and active stability, provide radiation in the range 205 nm to 100 nm with a linewidth of down to 10 kHz.

 

Nanosecond lasers
For users requiring high photon energy tunable radiation, the Photon Science Institute has two ns systems. Both are based on Nd:YAG pumped dye lasers, one with a parametric OPO with SHG and sum-frequency mixing for UV-visible output, whilst the other is configured for narrow linewidth IR operation via an OPO/A and difference-frequency mixing.

 

Ultrafast laser sources
Our ultrafast pulsed sources are suitable for applications spanning THz generation to ultrafast molecular kinetics and consist of six systems with broadly the following specifications:

 

  • 80 MHz, 100 fs, tunable from 690 to 1020 nm.
  • High repetition rate (~100 kHz), with extended tuning provided by 2nd and 3rd harmonic generation, two OPAs and DFG.
  • 1 kHz <40 fs, >6 mJ, again with 2nd and 3rd harmonic generation and with three white light seeded OPAs (two for UV and one for IR). There are plans for CEP stabilisation for this system.
  • 1 kHz, 130 fs system with two non-collinear OPAs and one white light seeded OPA.
  • 1 kHz, 1 ps system with SHG and OPAs for UV and IR operation. There is also a sum-frequency mixing unit for enhanced IR.
  • A large bandwidth oscillator producing <20 fs pulses at 800 nm.
