EPL SERIES Picosecond Pulsed Diode Lasers The EPL picosecond pulsed diode lasers are a family of high performance, cost effective excitation sources for fluorescence lifetime measurements. In Time-Correlated Single Photon Counting (TCSPC) they bridge the gap between the nanosecond flashlamp and expensive mode-locked Titanium sapphire femtosecond lasers. In addition, their external trigger capability enables their use as excitation sources in Multi-Channel Scaling (MCS) mode. The EPL lasers are pre-adjusted for an optimum pulse width, with particular attention paid to reducing a secondary shoulder characteristic of picosecond diode lasers. The output has a typical pulse width of less than 100 ps. The EPL lasers are robust, maintenance free, easy to operate and have proprietary beam conditioning optics. KEY FEATURES Optimised for TCSPC 15 pre-set repetition frequencies from 2.5 KHz to 20 MHz External trigger capability Spectrally purified output Fully integrated & compact design Extremely low RF radiation Optimised collimated beam Drive electronics included
