Ingaas absorption coefficient
Webb15 mars 1999 · InGaAs/InAlGaAs strained quantum well lasers with 1.3 µm wavelength have been realized on In0.31Ga0.69As ternary substrates for the first time, owing to the increased indium composition of the substrates. A temperature-insensitive slope efficiency of -0.007 dB/K has been observed. WebbThe absorption coefficient is proportional to the (n − 1)th power of the optical intensity. Examples of Multiphoton Absorption Multiphoton absorption processes are often involved in laser-induced damage when it occurs in transparent media.
