Methods for laser processing semiconductor materials for use in optoelectronic and other devices, including materials, devices, and systems associated therewith are provided. In one aspect, a method of minimizing laser-induced material damage while laser-texturing a semiconductor material can include delivering short pulse duration laser radiation to a target region of a semiconductor material to form a textured region having a reorganized surface layer, wherein the laser radiation has a wavelength from about 200 nm to about 600 nm and a pulse duration of from about 10 femtoseconds to about 400 picoseconds, and wherein defect density of the semiconductor material from beneath the reorganized surface layer up to a depth of about 1 micron is less than or equal to about 1012/cm3. |
