Fiber-MOPA sources of coherent radiation
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2010This paper presents the concept and design of medium to high power fiber radiation sources in MOPA (Master Oscillator Power Amplifier) configuration. Research results are presented on a two-stage power amplifier for MOPA applications for the third telecommunications window at 1550 nm based on active erbium-doped and erbium/ytterbium-doped fibers.

M2 of MOPA CuBr Laser Radiation
Optical and Quantum Electronics, 2007The beam propagation factor, M2 of the master-oscillator power-amplifier (MOPA) CuBr laser emission compliant with ISO 11146 is studied methodically. Statistical parameters of 2D intensity profile of the near and far fields of MOPA laser radiation are measured by a beam analyzing technique as functions of timing delay between MO and PA.

MOPA pulsed fiber laser for silicon scribing
Optics & Laser Technology, 2016Abstract A 1064 nm master oscillator power amplifier (MOPA) pulsed fiber laser is developed with flexible control over the pulse width, repetition frequency and peak power, and it is used to investigate the dependence of mono-crystalline silicon scribe depth on the laser pulse width, scanning speed and repeat times. Experimental results indicate that
