摘要	A laser device which repeats a cycle of burst mode operation in each of which continuous oscillating operations for continuously pulsatively oscillating laser light by a prescribed number of times and stopping operations for stopping the pulsative oscillation for a prescribed pausing time are alternately executed, controls the power supply voltage of the laser device so that each output energy of the pulsative oscillation can become coincide with a target value, finds the difference between the output voltage of each pulse and the target value at every pulse and, for a pulse for which the difference exceeds tolerance limits, corrects and updates the power supply voltage value stored in the voltage data table means corresponding to the pulse number of the pulse and the measured oscillation pausing time by using the control gain of a control gain setting means set in the block corresponding to the pulse number and the measured oscillation pausing time and the difference, so as to always make the pulse energy of all pulses for the continuous pulsative oscillation constant and further improves the accuracy of optical machining.
其他摘要	一种激光装置，其重复突发模式操作的循环，其中每个连续振荡操作用于连续脉冲振荡激光达规定次数并且停止操作以停止脉冲振荡达规定的暂停时间交替执行，控制功率激光装置的供电电压使得脉动振荡的每个输出能量可以与目标值一致，找出每个脉冲的输出电压与每个脉冲的目标值之间的差值，对于差值超过的脉冲通过使用在对应于该块的块中设置的控制增益设置装置的控制增益，公差限制，校正和更新存储在电压数据表中的电源电压值，该电压值对应于脉冲的脉冲数和测量的振荡暂停时间。脉冲数和测得的振荡暂停时间和差值，以便始终如一使连续脉动振荡的所有脉冲的脉冲能量保持恒定，并进一步提高光学加工的精度。
