Picosecond pulsed diode lasers offered at 450 and 645 nm

PicoQuant has extended the already large number of available wavelengths of picosecond pulsed diode lasers with the release of a new laser head at 450 nm and a very much improved laser head at 635 nm. Both laser heads can be controlled by the established laser drivers of the PDL-Series.

PicoQuant has extended the available wavelengths of picosecond pulsed diode lasers with the release of a new laser head at 450 nm and a very much improved laser head at 635 nm. The laser at 450 nm features pulse widths shorter than 70 ps and an average output power up to 5 mW at 40 MHz repetition rate. The new laser head is also available in a dual mode version that allows picosecond pulsed as well as continuous-wave operation with an output power of up to 10 mW. The laser at 635 nm is now available in an improved version with much higher average output powers up to 20 mW at 80 MHz repetition rate. The laser head features pulse widths <90 ps and up to 50 mW output in continuous wave. These new laser heads open the door for a variety of new applications in bioanalytics, biochemistry, genetics, semiconductor characterization and quality control.

PRESS RELEASE

Picosecond Pulsed Diode Lasers at 450 nm and 635 nm PicoQuant has again extended the already large number of available wavelengths of picosecond pulsed diode lasers by the release of a new laser head at
450 nm and a very much improved laser head at 635 nm. Both laser heads can be controlled by the established laser drivers of the PDL-Series.

The laser at 450 nm closes the gap between the already long time available wavelengths of 440 nm and 470 nm. It features pulse widths <70ps and an average output power up to 5 mW at 40 MHz repetition rate. The new laser head is also available in a dual mode version, that allows picosecond pulsed as well as continuous-wave operation with an output power of up to 10 mW.

The laser at 635 nm is now available in an improved version with much higher average output powers up to 20 mW at 80 MHz repetition rate. The laser head features pulse widths <90 ps and up to 50 mW output in continuous wave operation.

The availability of these new laser heads open the door for a variety of new applications in bioanalytics, biochemistry, genetics, semiconductor characterisation and quality control. The laser heads are very well suited for exciting fluorescent proteins such as CFP or widely used fluorescent dyes such as ATTO 465 and are alternatives to frequency doubled solid state lasers or argon-ion lasers in applications like fluorescence microscopy or fluorescence spectroscopy. 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.
