Abstract: The gain of a GLS-23 neodymium phosphate glass is measured at a wavelength of 1.047 μm of a Nd³⁺:YLiF₄ laser. Linear gains of 0.035 – 0.036 cm^-1 are obtained for the active rod of length 13 cm pumped by 225 J, which points to the possibility of fabricating high-power lasers at this wavelength.
