A laser oscillator support table includes a base, a fixed plate supported over the base with intermediary of a Z-axis direction movement unit, and a Y-axis direction moving plate mounted on the fixed plate, movable orthogonal to an X-axis direction. An optical path direction of the beam emitted from a laser oscillator supported by the laser oscillator support table is defined as the X-axis direction. The laser oscillator support table further includes a rotating plate that is mounted on the Y-axis direction moving plate rotatably around a rotation center pin fixed to the Y-axis direction moving plate and supports the laser oscillator, a Y-axis direction movement unit that moves the Y-axis direction moving plate in the Y-axis direction, and a rotational movement unit that rotates the rotating plate around the rotation center pin in a plane parallel to a plane formed by the X-axis direction and the Y-axis direction.

In some embodiments, an ophthalmic laser system may be provided that does not include a traditional laser console. Instead, the treatment device may be configured to house the treatment light source within the device handle. Additionally, in some embodiments, the handheld treatment device may include a user interface, such as dials and buttons, for adjusting various parameters of the therapeutic light. With certain embodiments, the self-contained handheld treatment device may be operated independent of an AC power source. For example, in some embodiments, the handheld treatment device may be battery powered. Additionally, the handheld treatment device may be disposable or may utilize replaceable distal tips in certain embodiments. Certain embodiments may be particularly designed for transscleral cyclophotocoagulation. Also, treatment guides are provided that may be configured to couple with a treatment device to align the device with a target tissue of the eye.

A device for recording information in a data carrier, comprising a data carrier receptacle for partially receiving the data carrier in a planar manner; a data carrier cover arranged relative to the data carrier receptacle, which is designed for holding the data carrier between the data carrier receptacle and the data carrier cover; a laser source for the controlled emission of a laser beam designed to effect irreversible changes of the data carrier with the laser beam; and a mount that receives the data carrier receptacle to be pivotable about a pivot axis. The data carrier receptacle has two or more positions, that allow the data carrier receptacle to be received in the mount in such a way that the data carrier receptacle can be repositioned about the pivot axis in a pivotable manner.
