Abstract: The first modified neodymium yttrium aluminum borate (M-NYAB) self-doubling laser pumped by LD has been designed. The properties of the lasers are much better than those of NYAB self-doubling lasers pumped by LD. All of the M-NYAB self-doubling lasers pumped by LD can operate in TEM$-00$/ mode and the pumping threshold is less than one-third of that of LD pumped SFD laser with NYAB. The pumping threshold, maximum output power, and slope efficiency are 3.6 mW, 29 mW, and 4.8%, respectively. !3
