Picosecond Pulsed Diodes and LEDs

Compact and reliable turn-key diode laser solutions work in picosecond pulsed, modulated, or fast-switched (nsec to µsec) operation mode.

The PicoQuant group was founded in 1996 to develop robust, compact, and easy to use time-resolved instrumentation and systems. Our intention is to offer state-of-the-art technology, which has been co-developed and tested by renowned researchers, at a price affordable to scientific groups and cost sensitive industry.

PicoQuant's compact and reliable turn-key diode laser solutions work in picosecond pulsed, modulated, or fast-switched (nsec to µsec) operation mode. The laser systems typically consist of a common driver unit and exchangeable heads. Specialized lasers are also available as stand-alone units.

Picosecond Pulsed Drivers

The picosecond pulsed diode laser drivers are designed as universal units that can control the dedicated laser or LED heads offered by PicoQuant. All drivers permit to control repetition rate and pulse energy of the attached heads. The drivers are available as single channel or multichannel units with manual or computer control. Their high quality and reliability are expressed by a unique 5-year limited warranty.

Picosecond Pulsed Sources

The picosecond pulsed sources are either laser diode based or LED based devices that can be operated at variable, user-adjustable repetition rates up to 100 MHz. They cover discrete wavelengths from 255 nm to 1990 nm. Power levels vary between µW and hundreds of mW for the most powerful, fibre amplified versions. Pulse widths can be as short as 40 ps.
