Abstract

It is well known that excited-state absorption (ESA) at the laser wavelength is a limiting factor to the use of many gain media.1−3 Although ESA at 1.06 μm has been found to be weak in neodymium (Nd)-doped crystals,4,5 the broadband transitions associated with Nd-doped glasses allow a best overlap with the 4F3/2 and the higher excited levels.
