چکیده
Lowest-order, single-mode laser oscillation is reported in gain-guided index-antiguided fiber lasers having core diameters from 100 to 400 microm. A model is presented explaining how to select resonator mirrors to assure single-mode operation.

Gain-guided, index-antiguided fiber lasers
ecent experimental results [1,2] suggest that optical fiers having a negative index step from cladding to core, ombined with an adequately large gain coefficient in a arge-diameter core region, can provide robust single ransverse mode operation having very large mode area ithout requiring complex fiber structures or other mode iscrimination measures. This paper reviews the imporant mode propert...
متن کاملLasing in a gain-guided index antiguided fiber
fiber with a cladding index of refraction larger than that f the core is an index antiguiding (IAG) fiber. In such a ber total internal reflection at the core–cladding interace does not take place. Light generated in the core of the ber can leak out into the cladding of an IAG fiber, though t experiences some guiding by grazing angle reflection. here is some loss on each reflection, but if ther...
متن کاملGain saturation in gain-guided slab waveguides with large-index antiguiding.
We investigate numerically and analytically the effects of gain saturation on the propagation of the fundamental mode in a gain-guided index-antiguided slab waveguide. The propagating mode adapts to gain saturation by becoming less confined, while at the same time its peak intensity increases more slowly. At steady state, both the mode shape and the power remain constant.
متن کاملGain guiding in large-core Bragg fibers.
We theoretically analyze gain guiding in large-core Bragg fibers, to be used for large-mode-area laser amplifiers with single-transverse-mode operation. The signal is gain-guided in a low-index core, whereas the pump is guided by the photonic bandgap of the Bragg cladding to achieve good confinement. The high-index layers in the Bragg cladding are half-wave thick at the signal wavelength in ord...
متن کاملPower characteristics of homogeneously broadened index-antiguided waveguide lasers.
A model is reported that describes a bidirectional homogeneously broadened index-antiguided (IAG) slab laser having arbitrary single-pass gain and distributed losses. Maximum extraction efficiency and corresponding optimum output coupling are determined for various values of unsaturated gain and loss per pass. A method is proposed to determine the intrinsic laser parameters from output power me...
