The detector is based on a silicon-based avalanche photodiode with 1064 nm enhanced response and high gain response for atmospheric aerosol radar
they are widely used in coherent detection applications for distributed fiber optic sensing, and in scenarios such as wind measurement radar.
Small signal EDFA erbium-doped fiber amplifier is used to amplify weak light signals or as a preamplifier for weak light detection, and is widely used in fiber optic sensing systems and fiber optic communication network systems.
The module integrates both an EDFA erbium-doped fiber amplifier and a Raman fiber amplifier inside the module, which significantly reduces system complexity, increases reliability, and reduces size compared to conventional EDFA and Raman amplification systems. The front-end EDFA is available as a pulsed EDFA or an amplified EDFA suitable for ultra-long-range fiber optic sensing systems or high-speed fiber optic communication systems.
Pulsed EDFA erbium-doped fiber amplifier, C-band, commonly used after the acousto-optic modulator to achieve the amplification of pulsed optical signals, common in distributed fiber optic sensing systems, LIDAR and other applications.
APD430 series of free-space APD photodetector modules, wavelength range covering the visible and near-infrared region, can be used to replace Thorlabs the same model parameters; suitable for free-space optical applications detection, such as LIDAR.
The YB-LASER-1550-1 is a human-eye safe 1550nm high peak pulsed laser that achieves kW-level peak power, ns-level pulse width laser output, and self-monitoring light, making it ideal for use as a TOF LIDAR emission source.
EDFA as a preamplifier for photoelectric detection applications to achieve the amplification of weak light signals can greatly avoid the introduction of noise. After amplification, a PIN-type photodetector is used to realize the photoelectric conversion. The PIN detector is simple in structure, more linear and more adaptable to temperature.
