LED, picosecond & calibration sources
Picosecond Pulsed Diode Sources
Compact pulsed laser-diode sources with internal repetition-rate settings and external triggering. A synchronisation output connects the excitation source to time-resolved detection electronics.
Best suited to
Fluorescence lifetime, time-resolved spectroscopy and synchronised pulsed excitation.
Selecting a configuration
Specify wavelength, average power, pulse width and timing interface. Peak optical power and average optical power are separate specifications.
Measurement & configuration
- Typical 50 ps pulses; published maximum below 100 ps.
- Ten internal rate settings from 10 Hz to 20 MHz.
- External single-shot to 20 MHz triggering and a synchronisation output.
