Picosecond Pulsed Diode Laser for Fluorescence Applications

The Photonics Division of Edinburgh Instruments has announced the availability of the EPL 515 picosecond pulsed diode laser. Emitting at a nominal 512 nm wavelength, this is the latest addition to the range of EPL diode lasers which are optimized for Time Correlated Single Photon Counting (TCSPC).

The EPL 515 is a compact, robust, maintenance free, fully integrated system. It is pre-adjusted for an optimum pulse width of 150 ps at 10 MHz, and features 10 pre-set repetition frequencies from 20KHz to 20MHz.

EPL diode lasers provide a cost-effective and reliable alternative to nanosecond flash lamps and expensive mode locked Titanium Sapphire femtosecond lasers. The new EPL 515 brings an additional wavelength into the range, allowing more fluorescent dyes to be excited and further extending the range of applications, which include fluorescence lifetime measurements that use TCSPC as the measurement technique.

Typical instrumentation in which the EPL 515 may be used are fluorescence lifetime spectrometers and fluorescence lifetime multiwell plate readers for spectroscopy applications in biochemistry, biology, photophysics, semiconductor physics, bio-chemical assays etc. Customized versions of the diode laser can be also supplied for integration within various types of analytical instrumentation.
