Abstract:
An optical amplifier comprising:a first slab of a solid state lasing material having a generally rectangular cross-section, defining a first major axis and longitudinal axis, said first slab defining opposing end faces and four lateral surface;a second slab of a solid state lasing material having a generally rectangular cross-section defining a second major axis and a longitudinal axis, said second slab defining opposing end faces and four lateral surfaces said first and second axis configured such that their respective longitudinal axes are generally coaxially aligned, said first and second slabs configured to reflect light entering one of the end faces in a zig zag pattern;first and second pumping sources applied to two opposing lateral surfaces of said first and second slabs;first and second cooling means applied to said two opposing lateral surfaces of said first and second slabs; anda polarization rotation device disposed between said first and second stabs.
