A storage stores the monitoring data. A display displays a laser output verification screen that includes a display of a portion of the monitoring data. The main controller can switch the display mode in which the laser output verification screen is displayed between a first display mode in which only first display data from the monitoring data is displayed and a second display mode in which at least second display data from the monitoring data is displayed. The first display data includes data that makes it possible to verify the output state of the laser light and data that makes it possible to verify settings related to the output of the laser light. The second display data is data that is different from the first display data. ## Claims ### Claim 1 A laser processing device that processes a workpiece with a laser beam, the laser processing device comprising: a laser light source configured to emit the laser beam; a controller configured to control the laser light source and obtain monitoring data on the laser processing device; storage that stores the monitoring data obtained by the controller; and a display configured to show a monitoring data display screen that includes presentation of at least part of the monitoring data in accordance with a control executed by the controller, wherein the monitoring data includes first display data and second display data, the controller is configured to switch a display mode in which the monitoring data display screen is displayed between a first display mode that shows only the first display data in the monitoring data and a second display mode that shows at least the second display data in the monitoring data, the first display data includes data that allows an output state of the laser beam to be checked and data that allows a setting related to an output of the laser beam to be checked, and the second display data differs from the first display data. ### Claim 2 (depends on 1) The laser processing device according to claim 1, wherein the second display data includes data for checking whether the laser processing device has an anomaly. ### Claim 3 (depends on 1) The laser processing device according to claim 1, wherein the second display mode shows the first display data and the second display data. ### Claim 4 (depends on 1) The laser processing device according to claim 1, wherein the controller executes an authentication process that permits the display to show the monitoring data display screen in the second display mode, and when the monitoring data display screen is permitted to be shown in the second display mode on the display by the authentication process, the controller shows the monitoring data display screen in the second display mode on the display. ### Claim 5 (depends on 4) The laser processing device according to claim 4, wherein the display shows a screen including a password input section into which a password is input, and the authentication process includes a password authentication process that verifies the password input into the password input section and a password stored in advance in the storage. ### Claim 6 (depends on 1) The laser processing device according to claim 1, wherein the first display data includes measured data obtained by actually measuring the output of the laser beam, correction rate data for correcting the output of the laser beam, and accumulated time data on time for processing with emission of the laser beam. ### Claim 7 (depends on 1) The laser processing device according to claim 1, wherein the laser light source includes a laser oscillator that outputs the laser beam, and the second display data includes internal temperature data on the laser oscillator.
