Non-Gaussian fundamental mode patterns in narrow-stripe-geometry lasers

Near- and far-field patterns of narrow (⩽10 μm) stripe-geometry lasers are reported which differ significantly from the Gaussian patterns predicted and observed in wider-stripe lasers. The field patterns are explained by using a waveguide model which takes into account the finite extent of the strip...

Description
Summary:Near- and far-field patterns of narrow (⩽10 μm) stripe-geometry lasers are reported which differ significantly from the Gaussian patterns predicted and observed in wider-stripe lasers. The field patterns are explained by using a waveguide model which takes into account the finite extent of the stripe. High-output-power operation in a single fundamental transverse and lateral mode (up to 1 W in 25-ns pulses) has been observed in devices of this type.
