  • EPL 515-nm Picosecond Pulsed Diode Laser
Nov 2011

LIVINGSTON, Scotland, Nov. 29, 2011 — Edinburgh Instruments Ltd.’s Photonics Div. has announced the availability of the EPL 515 picosecond pulsed diode laser. Emitting at a nominal 512-nm wavelength, it is the latest addition to the family of EPL diode lasers that are optimized for time-correlated single-photon-counting (TCSPC) applications.

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

The company says that the EPL diode lasers provide a cost-effective and reliable alternative to nanosecond flashlamps and expensive mode-locked Ti:sapphire femtosecond lasers. The new model 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 it can be used are fluorescence lifetime spectrometers and fluorescence lifetime multiwell plate readers for spectroscopy applications in biochemistry, biology, photophysics, semiconductor physics and biochemical assays. Customized versions of the diode laser can be supplied for integration within various types of analytical instrumentation.
