Three lasing lines were observed under optical pumping in a T-wire laser with high uniformity at 4K. As such, the microscopic images of each emission peak were measured. Origins of the three lasing lines were assigned: low-energy lasing L1 was due to the T-wire ground states, middle-energy lasing L2 was most probably due to the core-arm well, and high-energy lasing L3 was due to the stem wells.
