New Pulsed Light Sources for Time-resolved Photoluminescence Spectroscopy
Sep 29 2021
A series of pulsed light sources for time-resolved photoluminescence spectroscopy has been launched by Edinburgh Instruments. The VPL, VPLED and HPL series of pulsed diode lasers and LEDs expand the range of compact, monochromatic sources on offer, while the AGILE supercontinuum laser provides tunable picosecond pulses across the visible and NIR regions.
Designed for time-Correlated Single Photon Counting (TCSPC) from picoseconds to microseconds, these HPL diode lasers are fully compatible with Edinburgh Instruments systems. Thanks to their high repetition rates up to 80 MHz and high-power output mode, they are the perfect choice for challenging samples with low brightness.
For longer decay times, the VPL and VPLED series may be used. The pulse width of these sources can be varied from 50 ns up to 1 ms so they are ideal 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 up to >2,000 nm removing the need for multiple monochromatic sources.
Roger Fenske, CEO, said: “We are excited to expand our portfolio with this new range of pulsed light sources. This will help meet the ongoing requirements of our customers and will bring added capability and functionality to their work procedures.”
