Efficient beam-correcting holographic collimator for laser diodes.
We describe a method for recording a beam-correcting holographic collimator for laser diodes in the presence of recording-to-readout wavelength shift. An astigmatism-correcting, beam-shaping hologram recorded with this method at 488 nm displays a high-efficiency, near-diffraction-limited collimation of a diode beam at 820 nm.
