GaAlAs/GaAs laser phased arrays for pumping Nd~+-doped solid laser are described in this paper. Ten-ele-ment arrays have been fabricated by using oxide mask and zinc diffusion stripe geometry structures. The lasing wavelength is in the range of 809±5nm, and the output power is over 200mW. They have been used for pumping Nd:YAG and Nd-glass lasers.
