A laser beam machine includes: a laser oscillator that outputs laser light; a transmission fiber through which the laser light output from the laser oscillator propagates; a first adjuster that is disposed between the laser oscillator and an incidence end of the transmission fiber and changes an incidence numerical aperture of the laser light incident to the incidence end of the transmission fiber; a second adjuster that converges the laser light and changes a zoom magnification of the laser light between an emission end of the transmission fiber and a workpiece; and a controller that performs adjustment of a beam diameter of the laser light at an image forming position of the laser light and adjustment of an emission numerical aperture of the laser light emitted from the emission end of the transmission fiber independently of each other, by changing the incidence numerical aperture.

Laser beam machine and method for controlling laser beam machine

A multiplexing optical system includes a light source, a lens and a lens array. The light source includes a plurality of light emitting elements of surface emitting lasers. The lens is configured to change and condense optical paths of laser light beams emitted from the light emitting elements. The lens array includes a plurality of lens regions arrayed so as to correspond to respective optical paths of the laser light beams changed by the lens, and is configured to condense the laser light beams by the lens regions to form a multiplexed beam.

Multiplexing optical system

A laser module includes: a photonic crystal surface-emitting laser element; a collimating lens array for producing a parallel optical beam; a condenser lens for condensing the optical beam; and an optical fiber which receives the optical beam on one end and transmits the optical beam to the outside. In the collimating lens array, an aperture portion corresponding to a collimating lens allows passage of the optical beam with an energy of not less than 94.0% and not more than 99.5% with respect to 100% of the energy of the optical beam incident on the collimating lens array.

Laser module and laser processing apparatus

A generation device according to the present application includes a storage unit and a generation unit. The storage unit stores information regarding an authentication module that carries out the authentication based on a result of the verification between registration data registered in advance and predetermined input data. The generation unit controls the generation of authentication result information which is information generated from the verification result acquired from the authentication module while serving as information to be processed through a specific authentication procedure used between the generation unit and an authentication server that carries out the personal authentication of a user using the authentication module.
