LASERS, DETECTORS

A 28-page full-color booklet from Photonic Solutions plc details a selection of lasers, including the tunable, ultrafast, small and large gas, and pulsed and diode-pumped solid-state varieties from suppliers such as Continuum and PicoQuant. It describes IR photodetectors from Vigo System Ltd., an avalanche photodiode module from Licel and ultrasensitive germanium detectors from Edinburgh Instruments. A section on spectroscopy presents Becker & Hickl’s time-correlated single-photon-counting modules and Eksma’s sum frequency generation spectroscopy technique. Accessories such as laser crystals and precision optics from Casix and laser attenuators and polarizers from Lasnix also are showcased.
