Experimental and Theoretical Study of CO(2) Staggered Hollow-Bore Array Lasers
Abstract
Experimental and theoretical investigation of CO2 staggered hollow- bore (SHB) arrays were conducted with the main objective of gaining a better understanding of the device. By focussing on the effects of a mirror tilt on the output power, the near field and pairwise far field patterns, were have deduced that the effective cavity length variations, manifested primarily through mode mismatch loss, are responsible for many of the observed features of phase-locked SHB arrays. We also found that by making one of the elements very lossy, we can effectively shut down the entire array, which could have a potential application as a novel amplitude modulation technique. Keywords: Arrays; Waveguide, Laser, Optical, Staggered, Hollow bore.
