1064nm Laser Detection and Guidance
SEMICOA's 1064nm tuned photodetectors are designed specifically for laser detection and guidance.

Spectral Sensitivity Conditions
Spectral Sensitivity measurements were made with an illuminating spot of 5 mm in diameter. The spectral width was 2nm.

Quantum Efficiency Conditions
Quantum Efficiency measurements were made with an illuminating spot of 5 mm in diameter.The spectral width was 2nm.

Pulse Response Conditions
Pulse response measurements were made with the reverse bias high potential applied to the anode while detecting the photocurrent (voltage across 50-Ohm resistor).

Laser Pulse Source
Q-switched Nd:YAG laser
