Power Stabilization of the Dual-Mode Laser Using Volume Holographic Gratings

From Ondax, Inc.
 

 

We present a power stabilization method for a dual-mode Ti:Sapphire ring cavity laser. Without stabilization, mode competition caused the output power of the two modes to fluctuate by approximately 10 dB. The power stabilization system, which used volume holographic gratings to monitor the power in each mode, reduced the power flucuations to less than 3 dB.
