Optimised for MCS
14 Pre-Set pulse widths from 50 ns to 1 ms
External trigger capability
Adjust pulse width and repetition rate with input trigger pulse
Operation in CW mode
Spectrally Purified Output
Compact plug-and-play design
The VPL series of diode lasers provide variable width pulses in the ns to ms range, as well as CW operation with powers up to 60 mW.
They are optimised for long photoluminescence lifetime measurements using the Multi-Channel Scaling (MCS) detection method. The width of the excitation pulses is easily controlled from the VPL allowing quick optimisation of the measurement conditions.
The VPL lasers are compact, maintenance free, and user-friendly. Although they are designed to match Edinburgh Instruments spectrometers, they can be incorporated into any experiment thanks to their external trigger capability.
