LIGHT THERAPY

Light: the medicine of the future has arrived

Light as a therapy can heal injuries and reduce pain in humans and animals. James Carroll of THOR Photomedicine discusses the rapidly growing field of low level laser therapy.


ASK THE EXPERT

Ultrafast fibre lasers need insight for success

Marie Freebody speaks to Fianium's chief executive officer, Anatoly Grudinin, to find out how misconceptions about ultrafast fibre lasers are threatening their commercial success.


BIOPHOTONICS

Optical syringe aids studies of single cells

The next time you look at a list of microscope accessories, a photoporation module for cellular analysis could well be available. Jacqueline Hewett talks to Kishan Dholakia about the clinical and commercial potential of optical injection by photoporation.


FIBRE LASERS

Fibre lasers look to large mode areas

New approaches to obtaining diffraction-limited beams from large-mode-area fibres point to unprecedented ruggedness and output powers. Breck Hitz investigates.


TECHNOLOGY TUTORIAL

Optical interferometry for surface metrology

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision levels of optical interferometers for this application.


SOFTWARE

Optical modelling points the way to PDT progress

Off-the-shelf commercial software is helping scientists to enhance the clinical efficacy of photodynamic therapy for targeted tumour destruction. Joe McEntee reports.


BACK CHAT

Industry associations create stability during downturns

When it comes to surviving an economic downturn, industry associations offer strength in numbers. Tom Pearsall tells OLE how members of the European Photonics Industry Consortium are bearing up.
