Pulsed lasers are regularly used in bio-imaging using different fluorophores. Techniques such as stimulated emission and depletion (STED) microscopy, or fluorescence lifetime imaging (FLIM) require pulsed lasers of different wavelengths, best suited to the fluorophore being used. Unilumen Photonics specializes in pico-second pulsed lasers at 1070nm, 1310nm and 1550nm, which are frequency doubled to visible and near infra-red wavelengths. In addition to the lasers themselves, Unilumen Photonics also brings expertise in synchronized gated detection with avalanche photodiodes which provide better signal-to-noise ratios than conventional PMTs.
Fiber lasers typically have better beam quality, low maintenance, footprint and low cost of ownership compared to conventional bulk lasers. Such factors position fiber lasers as a tool of choice in medical applications including surgery, dermatology, gynecology, cardiology, dentistry, etc. Recent uses include the use of femtosecond fiber laser for cataract treatment, angioplasty, hotodynamic therapy (PDT), and diagnostic image processing. Unilumen Photonics current products focus on pulsed fibre lasers for urology and opthamology, at both 1.07um (infra-red) and 532nm (visible)
