Broad Portfolio of Picosecond Diode Laser Heads
The LDH Series offers a broad portfolio of picosecond pulsed diode laser heads spanning wavelengths from the UV to the NIR (375–1990 nm). Each diode laser head combines carefully matched drive electronics and optics to deliver clean, stable picosecond pulses with adjustable repetition rates up to 80 MHz. Multiple diode types, tapered-amplified options, and single-mode or multimode fibre coupling provide wide flexibility across time-resolved techniques such as FLIM, FCS, TRPL, and LiDAR.
Compatible Laser Drivers
The LDH Series is fully compatible with the PDL 800-D, Sepia PDL 810, and Sepia PDL 828 drivers. This ensures reliable operation across different pulse modes, repetition rates, and wavelength configurations, enabling straightforward integration into both single- and multi-wavelength experimental setups.
Suitable for All Major Scientific Disciplines
The LDH Series is widely used across life sciences, materials research, quantum optics, and advanced sensing. Its clean picosecond pulses, broad wavelength coverage, and flexible driver compatibility support precise excitation in fluorescence studies, single-photon experiments, and ranging applications — making it a reliable choice wherever controlled laser excitation is essential.
Single Mode and Multi Mode Fibre Integration
LDH laser heads can be equipped with optional fibre coupling into single-mode, polarisation-maintaining single-mode, or multi-mode fibres. Typical coupling efficiencies reach above 40% for single-mode and above 80% for multi-mode. Each configuration is prealigned before shipment to ensure stable output and reliable beam delivery for fibre-based setups.
