“…The calculation showed that in such devices one can achieve a phase modulation with π amplitude at the residual intensity modulation of no less than 0.8 dB. In [28], a 2π phase shift was obtained in a l mm long phase modulator with less than a 1.2 dB amplitude modula tion. In that device use was made of one negatively biased amplifier section.…”

A three-section optical diode amplifier is simulated, whose sections have different amplitude-phase coupling coefficients R (linewidth enhancement factors). We show that it is possible to change the output wave phase for a constant output power due to only a difference in the value of this coefficient. In a single-mode amplifier, the first section has a horizontal waveguide formed by the gain (gainguided), and the other two sections are formed by change of the refractive index (index-guided). The values of the current in the first two sections are found, at which the phase changes by more than 2π at a constant output power of 2W. Such amplifiers can be integrated into single-crystal bars, which makes them adaptive for use in kilowatt laser systems with a coherent combining of beams.

“…Two and threesection diode lasers were used in many works (see, for example, [21][22][23][24][25][26][27][28][29][30]). Much attention was paid there to the modulation characteristics.…”
