Abstract

We report on a coherent beam combination of three high-brightness tapered amplifiers, which are seeded by a single-frequency laser at λ = 976 nm in a simple architecture with efficiently cooled emitters. The maximal combined power of 12.9 W is achieved at a combining efficiency of > 65%, which is limited by the amplifiers’ intrinsic beam quality. The coherent combination cleans up the spatial profile, as the central lobe’s power content increases by up to 86%. This high-brightness infrared beam is converted into the visible by second harmonic generation. This results in a high non-linear conversion efficiency of 4.5%/W and a maximum power over 2 W at 488 nm, which is limited by thermal effects in the periodically poled lithium niobate (PPLN).

Fig. 2 Combined power at output and total combining efficiency as a function of the currents in the tapered section. The ridge currents were actively controlled in the range of 250 to 400 mA, the heatsink temperature was T = 20 °C. The astigmatism of the amplifiers was corrected at each operating current.

Fig. 3 Beam profiles at waist for (a) one individual amplifier A2, (b) CBC of two amplifiers A1+2 and (c) the final CBC step of all three amplifiers A1+2 + 3. Measurement for Itp = 10 A, T = 20 °C and actively controlled ridge currents in the range of 250 to 400 mA. The FA is in vertical and the SA is in horizontal direction. The given central lobe power content was calculated by fitting a Gaussian beam profile to the central lobe of the beam and calculating the power content within the fitted profile.
