Series 4X photodetectors are designed specifically for high-speed 1064 nm Nd:YAG laser pulse sensing. They offer high pulsed and DC responsivity at wavelengths up to 1100 nm, together with extremely low capacitance per unit area.
The detector structure is designed to be fully depleted at 150 V reverse bias, which supports fast response and stable performance in demanding laser applications. The Series 4X range includes single elements and quadrant detectors, giving flexibility for different beam sensing and positioning needs.
Key Features:
- Optimized for high-speed 1064 nm pulse sensing.
- High responsivity up to 1100 nm.
- Very low capacitance per unit area.
- Fully depleted at 150 V reverse bias.
- Available in single-element and quadrant formats.
- Optional guard ring connected on selected versions.
Applications include high-speed 1064 nm Nd:YAG laser pulse detection, pulsed laser monitoring, beam positioning, and other near-infrared sensing tasks where low capacitance and fast response are critical.
