Mode Hopping

The shifts of the wavelength position that a radiation mode jumps from one longitudinal mode to the next in semiconductor lasers have been studied. The variation of the gain curve is found to depend not only on the junction temperature but also on the carrier density. The mode hops occur at different wavelengths and temperatures as the injection current changes. A systematic approach to controlling the temperature and current could extend the wavelength tuning range to a much greater extent. A wider tuning range will provide a free-running diode laser capable of readily reaching the specific atomic or molecular transition.

PurposeAs an emerging measurement technique with the merit of easy alignment and high sensitivity, laser self-mixing interferometry (SMI) has wide applications in the detection of physical quantities. Considering that the characteristics of lasers have a determining influence on sensors’ performance, the authors have established an open cavity solid-state laser (SSL) with more adjustment flexibility to act as a laser source.Design/methodology/approachThe fundamental structure of a SSL has been presented with an Nd:YAG rod severing as an active material and a birefringent filter inserted in the resonator as a mode selecting element. The power stability has been tested by a power meter, while the mode pattern has been inspected with a scanning Fabry–Perot interferometer, and the linewidth has been observed through a wavelength meter. A loudspeaker driven by a function generator is located in the extracavity to introduce phase modulation for SMI signal observation.FindingsThe established Nd:YAG SSL operates in a single longitudinal mode with the power stability of 0.2 mW and the linewidth less than 10 MHz. The SMI phenomenon occurs in the SSL, and the SMI signal obtained shows a fine signal-to-noise ratio of about 30 dB.Originality/valueTo the authors knowledge, SMI sensors using SSLs, especially in open cavity type, have rarely been reported, and they can find significant applications in designing high performance SMI sensors and instruments.
