本文研究了具有亚微米厚度增益层的锥形微球系统的激光输出。对于增益层，采用溶胶-凝胶法在SiO2微球上制备了厚度为200 nm的掺Er ~（3+）的P_2O_5-Al_2O_3-SiO_2薄膜。用薄增益层的单模激光的演示表明，在P共掺杂增益层中的Er离子的色散得到改善。
Lasing of a taper-microsphere system with a gain layer of submicrometer thickness is demonstrated. For the gain layer, an Er3+-doped P2O5–Al2O3–SiO2 thin film with a thickness of 200nm was fabricated using the sol-gel method on a silica microsphere. The demonstration of single-mode lasing with the thin gain layer suggests the improved dispersion of Er ions in the P codoped gain layer.
