The diode laser and laser resonator for a diode laser with an improved lateral beam quality

摘要

Laser resonator for a laser diode, comprising:a gain section (gs),a first planar bragg reflector (dbr1) and a second planar bragg reflector (dbr2),the gain section (gs) has a trapezoidal shape,and the first planar bragg reflector (dbr1) at a first base side of the trapezoidal gain section (gs) and the second planar bragg reflector (dbr2) on the opposite base side of the trapezoidal gain section (gs) are arranged,characterized in thatthe entire gain section (gs) gain is designed to be guided, and the width (d1) of the first planar bragg reflector (dbr1) of the width (d2) of the second planar bragg reflector (dbr2), a distinction.
