摘要：

Efficient, guided-wave distributed Bragg reflectors were fabricated in potassium titanyl phosphate (KTiOPO4, KTP) by ion-exchange. The period of these gratings (0.7 mum) was chosen to provide third-order Bragg reflection of the TM00 mode at 860 nm. Gratings as short as 500 mum provided nearly 100% reflectivity. The reflection from an ion-exchanged grating was used to provide the feedback required for operation of an extended-cavity GaAlAs diode laser. Gratings as short as 70 mum provided adequate feedback for stable operation of the extended-cavity laser.
