摘要： Nano-particle based mode strippers for removing undesirable laser energy for laser systems. Nano-particle mode strippers having matched indices of refraction to the outer cladding remove cladding light converting it into heat. There are provided fibers having evanescent mode strippers having annular outer cores and claddings.
