Abstract
Great differences were found between the spectral and power responses for two modes of a single-heterostructure laser operation, with the dynamic behavior of each mode fitted to the traditional definition of the internal Q-switching phenomenon. The first mode is interpreted in terms of the most popular diffraction losses theory, while the other one is related to the practically important method of high-power picosecond optical pulse generation and interpreted in terms of a recent carrier heating and cooling model. This finding could obviate confusion in the interpretation of mechanisms of high-power picosecond pulse generation in the Q-switching mode.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.
