  • Pulsed Lasers: How to Choose the Right Fast

    The Ophir FPD-VIS-300 is a Silicon photodetector sensitive from 320 to 1100 nm with a 0.3 ns rise time, corresponding to a bandwidth of 1.2 GHz. Using a 2 GHz oscilloscope and a 50 Ω , 4 GHz BNC cable, we calculate our total system response time to be: which is faster than our requirement of 0.4 ns rise time.

  • Selecting a Photodetector: Using WITS$ as a Rough

    In summation, the incident light power must be greater than the minimum detectable power for the photodetector to be a viable selection. Figure 2 depicts the suitability of selecting a photodetector depending on the input light level. In it, the scaling for the top axis corresponds to the photon irradiance (number of photons•mm −2 •s −1).

    Si APDs are used when light signals are too high for photomultiplier tubes and too low for conventional photodiodes. Si APDs are often used in high-speed applications since the excess noise from the avalanche process is still lower than the noise that would be generated in connecting an external amplifier to a conventional photodiode operated at high frequencies.
