Sepia PDL 828

Sepia PDL 828 is a highly flexible multichannel driver designed for precise control of picosecond lasers and pulsed LEDs across a broad spectral range (266 – 1990 nm). Its modular architecture supports up to 8 independently addressable heads, enabling parallel excitation, complex pulse sequences, and rapid wavelength switching. A powerful oscillator module provides fine timing control, user-defined burst patterns, and picosecond-level delays, while the dedicated software and API allow seamless integration into automated measurement workflows. With intuitive USB operation and stand-alone capability, Sepia PDL 828 offers a robust platform for demanding multi-wavelength experiments in modern scientific research. A five-year limited warranty underscores its long-term reliability.

Advanced burst control enables tailored excitation schemes for materials with long-lived or hidden non-radiative states, where conventional repetition rates fail to capture relevant dynamics. Using the burst mode of the Sepia PDL 828, complex pulse sequences such as the Read–Write–Read approach can be implemented. These sequences are generated and precisely timed by the SOM 828-D oscillator module, which provides programmable delays and reliable synchronization across channels. A controlled burst of write pulses prepares a quasi steady state, followed by delayed readout pulses to probe carrier trapping and relaxation dynamics in time-resolved photoluminescence experiments.
