Nanosecond LED Excitation for Advanced Research

UV–Visible LED Sources with Flexible Pulse Control

The PLS-I Series provides high-power nanosecond pulsed LED sources spanning the UV to visible range from 355 to 600 nm in a compact and maintenance free design. Each LED head delivers short pulse widths, high repetition rates and strong average power in pulsed or CW operation. All parameters are controlled through the Taiko PDL M1, which enables linear mode, free trigger mode and max power mode for precise excitation workflows. This combination of spectral coverage, stable output and flexible timing makes the PLS-I Series ideal for a broad spectrum of research applications.

Seamless PLS-I Compatibility with Taiko PDL M1

The PLS-I Series is designed exclusively for the laser driver Taiko PDL M1, creating a next-generation platform for nanosecond excitation. Taiko provides fully calibrated operation, flexible linear and max-power modes, burst capability and intuitive local or remote control. This combination ensures stable, traceable excitation performance and brings LED-based time-resolved workflows onto the same modern driver architecture used for LDH-I laser heads.

High Pulsed and CW Output Power

High pulsed average power supports efficient excitation in both pulsed and continuous wave operation. Depending on wavelength, average power levels reach up to 300 µW, with typically around 80 µW in pulsed mode and several hundred microwatts in CW operation. At the same time, nanosecond pulse widths down to approximately 1 ns are maintained, with typical values ranging from 1 to 5 ns depending on operating conditions. This combination of output power and temporal control enables reliable excitation intensity while preserving well-defined timing characteristics.
