摘要
High-power over 7W is presented in a single-emitting GaN diode laser with optical-loss suppressed waveguide structure. Here, thick undoped optical waveguide eliminates undesired light leakage to the absorbing p-cladding layer and thus leads the device to a high slope efficiency operation. The diode laser pumped white spotlight illuminator achieves a luminous efficiency 51.3 lm/W at a flux of 861 lm.
