摘要： A corneal topographer based on conoscopic holography with partially coherent illumination. Corneal topographic measurements can be accomplished at a processing rate higher than the standard video rate of 30 Hz. The conoscopic measurements can be used in an opto-electronic servo to control a photorefractive keratectomy system in real time for an improved accuracy in laser ablation of a corneal surface.

摘要： Volume holographic gratings are used to spectrally combine the emissions from multiple sources into a single output beam. Transmission or reflection gratings are utilized with either laser diode bars, fiber lasers, or fiber collimated light sources. The volume holographic spectral combiner can also be used to feedback and stabilize the wavelength of the sources in an external cavity configuration.

摘要： The invention disclosed here teaches methods to fabricate and utilize a non-dispersive holographic wavelength blocker. The invention enables the observation of the Raman signal near the excitation wavelength (˜9 cm−1) with the compactness of standard thin film/holographic notch filter. The novelty is contacting several individual volume holographic blocking notch filter (VHBF) to form one high optical density blocking filter without creating spurious multiple diffractions that degrade the filter performance. Such ultra-narrow-band VHBF can be used in existing compact Raman instruments and thus will help bring high-end research to a greater number of users at a lower cost.

摘要： The invention disclosed here teaches methods and apparatus for altering the temporal and spatial shape of an optical pulse. The methods correct for the spatial beam deformation caused by the intrinsic DC index gradient in a volume holographic chirped reflective grating (VHCRG).The first set of methods involves a mechanical mean of pre-deforming the VHCRG so that the combination of the deflection caused by the DC index gradient is compensated by the mechanical deformation of the VHCRG. The second set of methods involves compensating the angular deflection caused by the DC index gradient by retracing the diffracted beam back onto itself and by re-diffracting from the same VHCRG. Apparatus for temporally stretching, amplifying and temporally compressing light pulses are disclosed that rely on the methods above.

摘要： A method is presented for shaping the spectral response of volume holographic grating elements by applying controlled thermal energy. The methods allow generating continuous or discontinuous grating periods from a fixed grating period. The methods are applicable to optical feedback into optical sources such as light emitting diodes, lasers and other general optical filtering applications.

摘要： A laser utilizes feedback from a volume holographic grating integrated in a collimating lens as a wavelength standard to lock the laser output wavelength to its desired value. This feedback is optical, wherein a volume hologram reflection grating is used to generate optical feedback into the laser gain region. Fabrication of the integrated volume hologram grating lens elements is by either first recording the grating in a rectangular parallelepiped of material and then shaping the lens from it, or alternatively by first shaping the material into the desired shape and then recording the grating with the use of an apparatus composed of an optical block within which a cavity is present to accept the lens and index matching fluid.

摘要： A laser utilizes feedback from a multiplexed volume holographic grating (VHG) as a stand alone element or integrated in a collimating lens as a wavelength standard to lock the laser output wavelength to its desired value. This feedback is optical, wherein a volume hologram reflection grating is used to generate optical feedback into the laser gain region. The multiplexed VHG can exhibit a variety of spectral bandwidth as a result of coherent superposition of the multiplexed gratings or the multiplexed VHG can replace individual VHGs that are used with several wavelength specific lasers.
