摘要：

LEDs have been created that emit in the region of the fundamental absorption band of methane at a wavelength of 3.3 mu m for fast-response gas analyzers, A continuous optical power of 0.13 mW (cw) is achieved, and the peak optical power is 2.2 mW (the pulsewidth is 50 mu s, and the inverse duty cycle is 1.6X10(2)). The current dependence of the optical power on the pump-pulse parameters is studied, and the conditions are found under which the peak power of the radiation of the LEDs in the mid-IR region is maximized.
