Edinburgh Instruments has introduced new pulsed light sources for time-resolved photoluminescence spectroscopy. The VPL, VPLED and HPL series of pulsed diode lasers and LEDs expand their range of compact, monochromatic sources, while the AGILE supercontinuum laser provides tuneable picosecond pulses across the visible and NIR regions.

The HPL diode lasers are designed for time-Correlated Single Photon Counting (TCSPC) from picoseconds to microseconds. They are suitable for samples with low brightness, thanks to high repetition rates up to 80 MHz and high-power output mode. For longer decay times, the VPL and VPLED series are available. The pulse width of these sources can be varied from 50 ns to 1 ms so they are suitable for Multi-Channel Scaling (MCS) measurements, providing higher pulse energies than picosecond lasers and LEDs. AGILE is a white-light picosecond pulsed laser available as a TCSPC source in the FLS1000 Photoluminescence Spectrometer. Coupled to the excitation monochromator in the FLS1000, its output wavelength can be tuned from <400 nm to >2000 nm removing the need for multiple monochromatic sources.
