Pulsed Laser Detector
Gigahertz-Optik Inc.Request Info
The ISD-1.6-SP-Vxx pulsed laser detector from Gigahertz-Optik Inc. is a microsphere-based detector for the fast, time-resolved power measurement of pulsed laser diodes and LEDs.
The device features a 16-mm diameter integrating sphere for the integration of laser modes and beam profile. Because of its small diameter, the temporal pulse deformations are smaller compared to those with larger diameters. As a result, pulses of a few nanoseconds in length are hardly deformed and can be measured in a time-resolved manner.
Two photodiodes in the 400- to 1100-nm spectral range are mounted to the sphere to form the complete compact integrating sphere detector assembly. The detector signal is processed using a P-9710 series optometer in pulse energy mode with pulse-stretching function. The absolute peak power can be calculated from the pulse energy and the relative pulse shape. Thus, the short duration light signal can be completely characterized.
