The 120-10034- 0001 (ET-3000) from Coherent Corp. is an InGaAs PIN Photodetector that operates at a wavelength of 1300 nm. It has a bandwidth above 2 GHz and an active area diameter of 100 μm. This photodetector has a maximum rise time of 17 ps and fall time of 175 ps. It has a responsivity of 0.9 A/W and an acceptance angle of up to 2. This photodetector has a noise equivalent power of 20 deg and maximum linear rating of 0.03 pW/sqrt(Hz). It has an optional fiber-coupled or free-space output and supports a BNC connector. This photodetector requires a DC supply voltage of 6 V and consumes 5 mA of current. It is ideal for monitoring the output of Q-switched lasers and mode-locked lasers.
