The high-power operation of the lateral mode stabilized 780-nm AlGaAs laser
diode (LD) with the window-mirror structure has been achieved. The stable
lateral mode operation up to 250 mW is realized. This is the highest power
record among the narrow stripe LDs with the wavelength of 780 mn. This LD i
s suitable for the next generation high-speed (16-24 x) CD-R/RW drives need
ing 200 mW class LDs.
