| 摘 要： | Thermal aberrations, thermal induced birefringence, anddamage of laser medium are well-known limitations forhigh power diode-pumped solid-state lasers. Severalnew types of lasers have been designed to solve theseproblems in the past years. Double-clad fiber laser withlarge ratio of surface to volume presents excellent coolingproperties[1]. Good beam quality is achieved by usingsingle-mode cores in the double-clad fibers. For a multi-mode core fiber laser, good beam quality can be obtainedby us… |
