Abstract: A machining process, associated with a workpiece, may include controlling, by a control device, a pulse repetition frequency (PRF) of an ultrashort pulse laser. The PRF may be controlled to maintain a substantially constant distance, on the workpiece, between adjacent pulses on a path. The substantially constant distance may be maintained despite changes in a speed of the path relative to the workpiece. An amount of energy of each pulse on the path may be substantially constant despite changes to the PRF associated with controlling the PRF.

Abstract: A device may include a transient optical amplifier having stored energy associated with a lower boundary and an upper boundary of a dynamic equilibrium, and a target level defining stored energy for amplifying a high energy input pulse to a higher energy output pulse. The device may include a pump to increase the amplifier's stored energy, and a source to pass low energy control pulses or the high energy input pulse to the amplifier. The device may include a controller configured to maintain the amplifier's stored energy in the dynamic equilibrium by requesting low energy control pulses for the amplifier at a high repetition frequency. The controller may wait to receive a trigger. Based on receiving the trigger, the device may stop passing low energy control pulses to the amplifier, and may pass the high energy input pulse to the amplifier when the amplifier's stored energy reaches the target level.

Abstract translation: 器件可以包括具有与动态平衡的下边界和上边界相关联的存储能量的瞬态光放大器，以及限定用于将高能量输入脉冲放大到较高能量输出脉冲的存储能量的目标电平。 该装置可以包括用于增加放大器存储的能量的泵，以及将低能量控制脉冲或高能量输入脉冲传递给放大器的源。 该装置可以包括控制器，其被配置为通过以高重复频率请求放大器的低能量控制脉冲来将放大器的存储能量维持在动态平衡状态。 控制器可能会等待接收触发。 基于接收到触发，器件可能会停止向放大器传递低能量控制脉冲，并且当放大器的存储能量达到目标电平时，可以将高能量输入脉冲传递给放大器。
