PowerPhotonic High Power Diode Correction Phaseplates null the laser beam wavefront error, restoring the intrinsic ex-facet brightness of the laser beam. These products provide near-diffraction limited performance in fast-axis collimated beams by decreasing beam divergence, improving beam homogeneity and coupled power, and increasing laser beam brightness by between 2 and 10 times.
Our Diode Correction Phaseplates compensate for smile errors due to emitter pointing variation, defocus and higher-order wavefront errors, and align all bars to a common boresight direction, resulting in a high-brightness beam with consistent pointing and divergence. Far field image data is processed remotely to create individually serialized optics that perfectly match the bar or stack.
The resulting collimation performance gives exceptionally well-controlled feedback in grating-stabilized applications resulting in high locking efficiency, increased locking range and predictable performance build after build.
