Coherent Beam Combining of Multiple Solid-state Lasers with Simplified Active Stabilization

The gain linewidth limits the scalability of combining multiple lasers by mutual injection locking. We propose a method to improve the scalability with a simple active stabilization scheme, and present results with Nd: YVO4 lasers. ©2006 Optical Society of America OCIS codes: (140.3580) Laser, solid-state
