1500-h continuous cw operation of double-heterostructure GaInAsP/InP lasers

Abstract
The first three double‐heterostructure GaInAsP/InP diode lasers to be life tested have so far logged over 1500, 1100, and 700 h, respectively, of continuous cw operation at room temperature without degradation. Their emission wavelength is 1.15 μm.
