Abstract :
We fabricated high power and narrow far-field angle, 1.5 μm eye-safe pulsed lasers with a flared ridge waveguide. High power (9.6 W) with narrow lateral far field divergence (3-4°), have been obtained. These devices will be applicable for free-space optical measurement systems as “eye-safe” light sources. Additionally, by decreasing perpendicular far field divergence, it is easy to collimate the output beam
