By: Shinobu Tamaoki Sumitomo Electric Inc. Pulse fiber lasers (PFL) have become widely popular for micro-machining applications due to their many benefits, such as the high beam quality, compactness, high wall-plug efficiency, and reliability. MOPA (Master Oscillator Power Amplifier) architectures, which provide temporal pulse shape control, are particularly interesting.

The Percussion Drilling of SI using a 20W MOPA Based YB Fiber Laser
By: Kun Li, William O’Neill, Jack Gabzdyl Institute for Manufacturing, University of Cambridge SPI Lasers The micro-machining of silicon components for use in the MEMS fabrication and microelectronics industry is well-established, and the demand for semiconductors started to recover after the 2008 downturn. Laser micro-drilled interconnect via holes is an application that has been applied […]
