Product Description

The HPL high repetition rate/high power picosecond pulsed diode lasers are a series of pulsed sources designed for Time-Correlated Single Photon Counting (TCSPC) measurements with repetition rates up to 80 MHz.

When operating in standard pulse mode, HPL lasers provide pulses of <150 ps making them the ideal source of measuring short fluorescence lifetimes.

For experiments that require higher excitation energy, the high-power operation mode may be enabled. This mode offers average powers of a few mW whilst maintaining sub-nanosecond pulse widths.

HPL lasers are designed with Edinburgh Instruments spectrometers in mind and are directly mounted onto their standard laser couplings, but they are fully independent and do not need an external controller. This, together with their external trigger capability, makes them easily integrated into any experiment.
