Extension of the Spectral Lasing Range of Semiconductor Lasers in the Dispersive Resonator

It is experimentally found that at the tuning of the laser diode lasing wavelength in a spectrally selective external resonator to the shortwave region of the spectrum a range of wavelengths is manifested for which lasing depends on the previous state of the system, namely, at the shortwave boundary...

Description
Summary:It is experimentally found that at the tuning of the laser diode lasing wavelength in a spectrally selective external resonator to the shortwave region of the spectrum a range of wavelengths is manifested for which lasing depends on the previous state of the system, namely, at the shortwave boundary of the lasing spectrum there is a region of 913 to 918 nm in which lasing occurs only under continuous operation conditions and only at the preliminary shift of the lasing spectrum from the lower-energy spectrum region. This effect is supposed to be due to the distortion of the gain spectrum of the active medium when lasing occurs in it.
