Abstract :
Summary form only given. The advantages of broad waveguide AlGaAs/GaAs SQW GRIN-SCH lasers for high-power operation are reported. The results show that the broadened-waveguide QW lasers are more suitable for high-power operation than lasers with conventional waveguide thickness and that the design of waveguides in the case of high-power laser diodes should be directed towards reducing both the optical losses and expanding the near-field pattern.
