HIGH POWER AND NARROW LATERAL FAR-FIELD DIVERGENCE 1.5-MU-M EYE-SAFE PULSED LASER DIODES WITH FLARED WAVEGUIDE

摘要

Pulsed laser diodes with flared waveguides operating in the 1.5-mu m eye-safe wavelength band are fabricated for the first time. High-power (9.6-W) operation with narrow lateral far-field divergence (4 degrees) has been obtained. These devices will be applicable for free-space optical measurement systems as 'eye-safe' light sources. References: 10
