    Abstract: In certain embodiments a method and system for laser-based material processing of a material is disclosed. In at least one preferred implementation temporally overlapping pulse series are generated with separate pulsed laser sources, for example nanosecond (NS) and ultrashort pulse (USP) sources (NS-USP). Pulses are delivered to the material as a series of spatially and temporally overlapping pulse pairs. The material can, but need not, be a transparent material. In some applications of transparent material processing, it was found the combination of pulses both substantially more material modification and high machining quality than obtainable with either individual pulse series taken alone. Other micromachining methods and arrangement are disclosed for formation of fine features on or within a substrate. Such methods and arrangements may generally be applied with a NS-USP combination, or with other sources.

    Abstract: A method and apparatus for detecting and controlling the conditions needed for starting and maintaining mode-locked operation of a laser system including a fiber oscillator and high power fiber amplifier. The invention is used to monitor the output power and repetition rate of the fiber oscillator and control the operation of the oscillator such that the oscillator obtains and maintains correct mode-locked operation despite changes in environmental conditions such as temperature, and also with changes due to component aging or degradation.
