Abstract
We present a coherent-beam-combining (CBC) experiment using a 795 nm
diode laser as a technique to achieve more power by combining two beams. Two
Gaussian beams are made to interfere while controlling polarization, amplitude and
their relative phase, in a modified Mach-Zehnder interferometer coupled with a
polarization interferometer. The output power is locked using a split detector, thus
stabilizing its performance and the final output. Next, we explore the polarization-
beam-combining (PBC) in this new setup, yielding an efficiency of 80.9% for CBC –
polarized light– and 91.7% for PBC – non-polarized light–. We ran a tapered amplifier
(TA), controlling its current, temperature and heat dissipation, whose mechanical
housing is currently in the optimization phase. In the sequel we shall be installing
a TA on each arm of the Mach-Zehnder interferometer to obtain a brighter source.
One interesting application of this work is its use in atomic-physics experiments (using
rubidium) and second order interactions in crystals.
