Reliable Picosecond Seed Lasers for Seamless System Integration

Compact OEM Laser Heads with Digital Control and Fiber Output

PicoQuant’s CPDL-S-F/FA Series offers compact picosecond seed lasers designed for seamless OEM integration. All parameters are controlled digitally via USB or RS-232, removing the need for an external driver and simplifying system architecture. Covering key wavelengths from 1030 to 1550 nm, with pulse widths around 100 ps (and down to 20 ps for selected models), the series delivers reliable timing, flexible repetition rates, and robust FC/APC fiber output for demanding amplifier chains and embedded photonics applications.

Optical configuration for TD-DCS measurements. An amplified picosecond seed laser illuminates the phantom. One SNSPD channel records the TPSF, while the second measures the IRF. The detected signals are processed via TDC cards and an FPGA-based processing unit. Adapted from Mazumder et al., Neurophotonics 8(3), 035005 (2021).

Picosecond Lasers for Advanced Optical Measurements

In neuroscience imaging setups, CPDL-S-F/FA lasers offer reliable picosecond excitation at 1030–1550 nm, ensuring clean temporal profiles and stable fiber delivery. Their compact OEM design simplifies integration into multimodal instruments that probe neural dynamics, perfusion changes, or optically driven physiological responses.

CPDL-S-F/FA lasers provide stable picosecond pulses and narrow-linewidth NIR output ideal for TD-DCS systems. Their precise timing, flexible repetition rates, and fiber-ready design enable accurate photon time-of-flight selection, supporting deeper sensitivity and improved blood-flow measurements in advanced neuromonitoring setups.

Stable Fiber-Coupled Output

Built on our proven diode-based platform, these narrow-linewidth NIR sources provide stable picosecond pulses with optional fiber amplification for higher output power. The FC/APC fiber output ensures reliable coupling into polarization-maintaining single-mode fibers, supporting consistent alignment, stable long-term operation, and straightforward integration into OEM architectures.
