Abstract

The overview of the phase-locking technique is presented. Analysis of the parameters that influence on the phase-locking is given. Admissible range of the deviation of the linear laser diode array, external cavity parameters is estimated. Comparison of the external Talbot cavity configuration with the other ones is held. Attention is paid to both investigation and employment of the laser diode arrays consisting of wide aperture lasers that opens an avenue to high power output radiation in a phase-locked mode. Special consideration is given to the cavity supermodes selection. Our experiments both confirm actual feasibility of 1D and 2D phase-locking of LDA's with specified parameters in the external Talbot (L_c equals Z_T/4) cavity and illustrate theoretical predictions of the system stability and selectivity, so that: (1) phase-locking in 1D configuration allowed diffractional limited lobes width (delta) (Psi) equals 0.5 mrad; (2) tilting of the output mirror provided 'in-phase' supermode selection; (3) phase-locking in 2D configuration of the two LDA's of N equals 8 lasers, separated by 1600 mkm resulted in diffractional lobes full width at half maximum (delta) (Psi) equals 0.5 mrad in slow axis and (delta) (Psi) equals 0.25 mrad in fast axis.
