Control of radiation parameters of pulse-periodic tunable diode lasers based on lead salts with double heterostructure

摘要

Spectral and power properties of the pulse-periodic tunable diode lasers based on lead salts with double heterostructure grown by MBE are considered. Procedure and criteria of preliminary selection of the laser samples are discussed. Typical characteristics of such lasers are presented. Methods for controlling the spectral and power properties in the pulse mode are considered. General mechanisms of laser wavelength tuning by current and temperature variations are demonstrated on the basis of experimental data. Methods for optimizing these parameters are considered.
