Abstract
Pulsed laser diodes with flared waveguides operating int he 1.5-μm eye-safe wavelength band are fabricated for the first time. High-power (9.6-W) operation with narrow lateral far-field divergence (4°) has been obtained. These devices will be applicable for free-space optical measurement systems as ‘eye-safe’ light sources.
