摘要： According to one embodiment, a laser recording device performs recording by irradiating a recording medium with laser light. The recording medium includes thermal recording layers including thermal materials with different color development threshold temperatures and stacked in an ascending order of the threshold temperatures of the included thermal materials from a surface irradiated with the laser light; and an intermediate layer provided between the thermal recording layers to perform thermal insulation and thermal conduction. The laser recording device includes a controller. The controller sets a power density of the laser light and an irradiation time and performs recording on the thermal recording layers by controlling irradiation with the laser light. The power density is relatively higher at recording of any of the thermal recording layers with a higher threshold temperature. The irradiation time is effectively longer at recording of any of the thermal recording layers with a lower threshold temperature.

摘要： A laser scanning unit for an image forming device includes a light source for emitting a laser beam, a scanning member having at least one reflective surface for scanning the laser beam onto an imaging surface across a plurality of scan lines, and driver circuitry for driving the light source to emit the laser beam. The driver circuitry has a first input for receiving a first signal indicating image information and a second input for receiving a second signal indicating shading information. The driver circuitry modulates the laser beam based on the first signal to form an image on the imaging surface corresponding to the image information and adjusts an output power of the modulated laser beam based on the second signal to substantially reduce energy variation across each scan line.

摘要： An image forming device includes a controller and a laser scanning unit. The laser scanning unit includes a light source for generating a laser beam for discharging a photoconductive member to create an electrostatic latent image. A first memory is housed on the laser scanning unit and stores data unique to the laser scanning unit and laser beam as characterized during production. A second memory in communication with the controller, and separate from the first memory, stores data characterizing a family of similar laser scanning units of a same type. The controller is configured to read both the first and second memories to generate data to compensate for energy variations along a scan path of the laser beam on the photoconductive member during use. The data substantially reduces energy variation from one scan path to a next.

摘要： A disclosed vertical cavity surface emitting laser device emits light orthogonally in relation to a substrate and includes a resonator structure including an active layer; and semiconductor multilayer reflectors disposed in such a manner as to sandwich the resonator structure between them and including a confinement structure which confines an injected current and transverse modes of oscillation light at the same time. The confinement structure has an oxidized region which surrounds a current passage region. The oxidized region is formed by oxidizing a part of a selective oxidation layer which includes aluminum and includes at least an oxide. The selective oxidation layer is at least 25 nm in thickness. The semiconductor multilayer reflectors include an optical confinement reducing section which reduces optical confinement in a transverse direction. The optical confinement reducing section is disposed on the substrate side in relation to the resonator structure.
