A hybrid incoherent sequence combining of pulsed lasers based on refraction-displacement-pulsed-combining and polarization beam combining

We present a novel approach for effective combining high-power lasers based on refraction-displacement-pulsed-combining and polarization combing. This approach allows combining of linearly polarization pulsed lasers with various repetition rates, pulse duration, and wavelength. In the experiment, three solid-state pulsed lasers is successfully realized a coaxial beam combining. The combining efficiency is 98.4%, and the diffraction limited times β keeps in about 4. This approach provides a feasible way to combine a large number of high average power lasers while keeping high beam quality.
