Single Channel Picosecond Excitation Made Simple

Precise Timing and Flexible Control in a Compact Driver

Sepia PDL 810 is a compact single-channel laser driver for precise picosecond excitation with minimal setup effort. It supports both pulsed and CW operation, offering fully USB-configured control over trigger source, repetition rate, and pulse energy. With timing options ranging from 2.5 MHz to 80 MHz and low-jitter performance, it adapts easily to diverse experimental demands. A broad selection of compatible light sources covering 266 to 1990 nm further enhances experimental flexibility. A crystal-locked oscillator, external triggering capabilities, and quick recall of predefined configurations ensure reliable, repeatable operation in any single-wavelength workflow. A five-year limited warranty underscores its long-term reliability.

LDH Series picosecond diode laser heads designed for seamless operation with PicoQuant's Sepia PDL 828, Sepia PDL 810 and PDL 800-D.

Broad Compatibility with Pulsed Light Sources

Sepia PDL 810 is compatible with PicoQuant’s LDH, LDH-FA, and PLS Series, enabling the operation of picosecond pulsed diode lasers and sub-nanosecond LEDs across a wide spectral range.
