Abstract
We have succeeded in bonding a Nd:YAG crystal and an anti-reflection coated diamond crystal to realize a composite laser which minimizes the Fresnel-reflection loss at the bonded interface for the first time. This newly developed composite laser has realized higher output power at higher pump power than a non-composite Nd:YAG laser while keeping nearly the same slope efficiency.Keywords
