Nv. Zotova et al., FIBEROPTIC DETECTOR USING A MIDINFRARED DIODE-LASER AND AN ACOUSTOOPTIC MODULATOR, Technical physics letters, 23(10), 1997, pp. 781-782
Data are given for an infrared detector based on a semiconductor injec
tion laser, which operates at a wavelength of 3.3 mu m and is coupled
by a chalcogenide optical fiber to an acoustooptic modulator made from
an amorphous Si-Te alloy. The beam modulation coefficient reaches 70%
for a pulse duration greater than or similar to 0.3 mu s, making the
detector well suited to gas-analysis applications. (C) 1997 American I
