Abstract
Mode expander isolator for a fiber laser amplifier comprising an optical fiber input, an optical fiber output, an isolator and at least one lens, the optical fiber input for coupling a first optical fiber with the mode expander isolator, the optical fiber output for coupling a second optical fiber with the mode expander isolator, the isolator being positioned between the optical fiber input and the optical fiber output for preventing back-reflected laser light from reaching the optical fiber input and wherein the isolator and the at least one lens form a free space mode expander.
