Abstract

The invention provides a command apparatus in a gas laser oscillator, capable of command at high speed and with high precision, comprising a plurality of discharging tubes and corresponding electrodes, a command generating section (5) generating commands for the laser power supplies; and a separating section (36) separating the generated commands into a bias command, an output command, an offset command and a gain command, wherein the bias command and the output command are common to the laser power supplies, the offset command and the gain command are defined at least in accordance with the discharge tubes corresponding to the laser power supplies respectively, wherein the command apparatus further comprises a transmitting section (37) transmitting, to the laser power supplies, the bias and the output command which are common to the laser power supplies and, transmitting the offset and the gain command defined at least in accordance with the discharge tubes corresponding to the laser power supplies respectively, corresponding to the laser power supplies. Therefore, base discharging and maximum injection power can be adjusted in a short time on the condition of existing a plurality of power supplies.

Description

technical field [0001] The invention relates to a command device in a gas laser oscillator. In particular, the present invention relates to a command device in a gas laser oscillator capable of high-speed and high-precision designation. Background technique [0002] Conventionally, gas laser oscillators have multiple laser power sources according to the required laser output. image 3 It is a figure which shows the example which has two laser power sources in the conventional gas laser oscillator. image 3 A gas laser oscillator 200 is shown with two laser power sources 110 , 120 . like image 3 As shown, the command created in the CNC is sent to the communication IC 350 of the output command device 100 and separated into a bias command 410 and an output command 420 . [0003] These commands are D / A-converted by the D / A conversion units 440a and 440b, respectively, and then added by the addition circuit 460. Next, the added analog command voltage is commonly sent to the re...
