Abstract: A broadband near-IR photodetector based on a large-area G12180-250A InGaAs photodiode (Hamamatsu) with a 5-mm-diameter photosensitive area was developed and tested. It is designed for detecting the IR luminescence of singlet oxygen. A circuit for signal amplification is assembled on the basis of broadband low-noise operational amplifiers with the subsequent filtering of a signal with an adjustable passband f varied from 15 to 600 kHz, thus allowing one to obtain a time resolution of better than 1 µs, a sensitivity level of 10 ⁷ –10 ⁹ V/W, and a noise equivalent power NEP [W/Hz ^1/2 ] ≈ 1.4 × 10 ^–14 λ ^–1 [µm] f [kHz] in a frequency band of 15–600 kHz.
