Multipath waveguide solid state laser or amplifier structure

摘要

A multipath waveguide solid state laser or amplifier structure has discrete active laser material regions (W1) arranged alongside and/or above one another in a solid state element (W2). Independent claims are also included for the following: (i) equipment for pump beam guiding in the above multipath waveguide solid state laser or amplifier structure; (ii) equipment for guiding a laser beam to be amplified in the above multipath waveguide solid state laser or amplifier structure; and (ii) a method of carrying out solid state laser or amplification operations using a solid state element as described above.
