Description

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. Technical Specifications CW Mode - Yes Bias Supply - 15 Vdc +/- 5%, 15W (2.1mm DC jack) Trigger Output - SMA, NIM Standard Interlock Input - Hirose HR10A-7P-4P(73), (Link pin 1 and pin 2 to ground – interlock healthy) Trigger Input - Hirose HR10A-7P-4P(73), (Signal pin 4 and ground pin 3) Trigger Input Signal - TTL > 50 ns pulse.
