Pyroelectric quadrant detector probes for pulsed-laser position sensing, tracking, and alignment include either a 9 or 20 mm2 detector with a four-channel preamplifier. They have a shielded cable, terminated into a locking, eight-pin LEMO connector. They handle wavelengths from deep UV to infrared, pulse rates to 1 kHz, and powers from microjoules to millijoules.

PRESS RELEASE
Spectrum Detector, Inc. Develops New Large Area Pyroelectric Quadrant Detectors for Pulsed Lasers
The new Quad Probes are designed for position sensing and tracking of pulsed lasers in real time …DUV to Far IR
Lake Oswego, Oregon, March 17, 2010 – Spectrum Detector, Inc., a leading designer and manufacturer of broadband Pyroelectric detectors and high performance power and energy meters for laser and THz sources, announces the development of a family of new Pyroelectric Quadrant Detector Probes for pulsed laser position sensing, tracking and alignment.
The two new probes include either a 9 mm or 20 mm square detector, mated to a fast, four channel preamplifier that integrates the laser pulses. The voltage output from each channel is proportional to the pulse energy and position of the laser pulse. The sum of channels A, B, C, and D equals the total pulse energy. The Quad Probes are compact and include a shielded cable, terminated into a locking, 8 PIN LEMO connector. The probes are designed for use stand alone or with our new four channel, digital instrument, DPQ-4Track, that will be available in April 2010.
The new Quad Probes are designed for position sensing, tracking and alignment of pulsed lasers from µJ to mJ, 1 to 1000 pps, and from DUV to Far IR. Position resolution of less than 10 um is possible but depends on the pulsed laser beam properties …like uniformity and spatial stability.
