PicoQuant has extended the number of available wavelengths of picosecond pulsed diode lasers by the release of a new laser head at 450 nm and an improved laser head at 635 nm. Both laser heads can be controlled by the established laser drivers of the PDL-Series. With pulse durations well below 100 ps, the pulsed lasers head perfectly matches the time resolution of mainstream detectors, yet at a price much lower than that of commonly used mode-locked lasers. The PicoQuant diode laser family (LDH Series) now covers the wavelength range from 375 to 485 nm and from 635 to 1500 nm. A special laser head at 531 nm has also been recently released. All laser heads come with collimator optics that can optionally be fitted with optical fibres.
