    摘要： The present invention is a novel multiple laser diode structure and method for using such structures to optically isolate the light from the different diodes. The novel structure comprises a submount on which the individual lasing elements are mounted and a back facet monitoring plate coupled to the submount. The back facet monitoring plate comprises a plurality of optically sensitive detectors that monitor the amount of laser light emanating from the back facet. Ideally, one detector should be mounted opposite a back facet for each lasing element. The submount is designed with an isolation bar that optically separates the light from individual lasing elements. The radiation thus detected by each detector emanates from the back facet of a single lasing element. The amount of back facet radiation captured by the detector is proportional to the amount of radiation emanating from the front facet of the lasing element. This information enables the system to individually monitor and subsequently control the spot power of the lasing element in a continuous closed loop fashion.

    摘要： Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a first surface of a porous substrate with radiation emitted by at least one flash lamp. The radiation flash heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the first surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate from the first surface.
