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

摘要

The present invention relates to a diode laser and laser resonator for a diode laser with an improved lateral beam quality without the use of an external resonator, in particular, the present invention relates to a wide strip laser with high output powers.It is an object of the present invention, a diode laser and a laser resonator for a diode laser, which, in the case of high output powers a high lateral beam quality, requires a small amount of adjustment and can be produced inexpensively.The structure according to this invention has a gain section (gs), a first planar bragg reflector (dbr1) and a second planar bragg reflector (dbr2), wherein 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, wherein the width (d1) of the first planar bragg reflector (dbr1) of the width (d2) of the second planar bragg reflector (dbr1), a distinction.
