摘要：
Data are given for an infrared detector based on a semiconductor injection 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.
