  • MOPA laser system with back reflection protection
    Patent number: 10749310
    Abstract: The invention relates to a MOPA laser system having at least one laser oscillator (MO), which generates laser radiation at an emission wavelength (?0), and having an optical amplifier (PA) downstream the laser oscillator (MO) in the propagation direction of the laser radiation, which optical amplifier amplifies the laser radiation and thereby spectrally broadens it to a useful bandwidth (??). It is an object of the invention to provide an improved MOPA laser system which is designed for a high power of the amplified laser radiation and which is insensitive to back-reflection. Unavoidable back-reflections should neither affect the output power of the optical amplifier (PA), nor lead to the destruction of the laser oscillator (MO) or other components of the system.
