Abstract
Experimental results on 1D and 2D phase-locking of laser diode arrays are presented. Attention is paid to the employment of the arrays consisting of wide aperture lasers diodes. Selection of the “in-phase” supermode, preferable for most of the cases, is attained in the external quarter Talbot (Lc=ZT/4=d2/2λ) cavity due to the output mirror tilt at the angle φm=λ/2d. Analysis of the parameters that influence on the phase-locking is given. Our experiments confirm theoretical predictions of the system stability and adequate selectivity for the laser diode array fill factor (FF) FF=0.6.
