Abstract
Wavefront measurements with large dynamic range on high-power diode lasers are demonstrated. The wavefront sensor exhibited a large dynamic range of π/2 to -π/2 and high accuracy of the wavefront slope angle of 0.05 degree. The result of this study may provide an accuracy method for measuring the wavefront distributions of the diode lasers and the light sources with large divergence angles, such as a 980-nm high-power diode laser.
