Abstract

We demonstrate enhancement in frequency doubling efficiency by coherent beam combining (CBC) of two high power tapered amplifiers The improved frequency doubling efficiency by CBC of two amplifiers is η=3.7%/W compared to single amplifier case where η=2.5%/W. This enhancement is due to the better beam quality achieved by CBC. 1.8 W of bluegreen light at λ = 488 nm is generated by single-pass second harmonic generation (SHG). The obtained results confirms CBC as a promising power scaling technique in frequency conversion applications.
