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.
