High-Power IR Picosecond Laser for Advanced Research

Flexible Pulse Control for Diverse Experimental Setups

VisIR is a versatile high-power IR picosecond laser offering flexible pulse control, precise timing, and broad wavelength coverage including 1064 nm and 1550 nm. Its Master Oscillator Fiber Amplifier (MOFA)-based design supports both narrow picosecond pulses (70 ps) and extended pulse operation up to ~0.5 ns, with adjustable pulse durations for optimized excitation or depletion conditions. Variable repetition rates from single shot to 80 MHz enable seamless adaptation to diverse experimental requirements. Whether used in advanced microscopy, ultrafast spectroscopy, or IR sensing, VisIR delivers stable, high-quality performance within a compact, stand-alone platform.

Quantum LiDAR using Entangled Photons

Light Detection and Ranging (LiDAR) is a method for determining ranges by targeting an object with a laser and measuring the time for reflected light to return. While being extremely successful, it struggles to distinguish genuine signals from background noise and potential jamming, especially in complex environments. It was recently demonstrated that utilizing spatio-temporal correlations inherent in entangled photons can effectively address these challenges. VisIR‘s short-pulsed emissions and high peak power allow for an efficient Spontaneous Parametric Down-Conversion (SPDC) in nonlinear crystals to generate entangled photon pairs with high stability, perfectly suited for applications in quantum imaging and secure sensing.

Enhanced STED Performance with Stable IR Depletion

High-power IR pulses and precise timing control open new possibilities for efficient depletion in STED microscopy. The nearly perfectly circular TEM₀₀ beam profile (M² < 1.1) of VisIR ensures clean donut formation, enabling accurate beam shaping and higher depletion efficiency. Stable 766 nm generation and adaptable repetition rates further support reproducible high-resolution imaging in demanding multi-laser environments.

Configurable Fiber Coupling

VisIR can be equipped with fiber coupling for single mode or multi-mode delivery. In practice the coupling reaches above 60 % for single mode fibers and above 80 % for multi-mode fibers. Each coupled unit is prepared and aligned to provide a stable and well controlled output at the fiber interface.
