High power continuous laser at 461 nm based on a compact and high-efficiency frequency-doubling linear cavity

Autor: Feng, Chen-Hao, Vidal, Sébastien, Robert, Paul, Bouyer, Philippe, Desruelle, Bruno, Prevedelli, Marco, Boullet, Johan, Santarelli, Giorgio, Bertoldi, Andrea

Publikováno v: Opt. Expr. 29, 27760 (2021)

A Watt-level continuous and single frequency blue laser at 461 nm is obtained by frequency-doubling an amplified diode laser operating at 922 nm via a LBO crystal in a resonant Fabry-P\'{e}rot cavity. We achieved a best optical conversion efficiency

Covid-19 and the Irish Border. A Preliminary Analysis of Cross-Border Cooperation Considering Health and Work Issues

Autor: Julien Guillaumond, Vanessa Boullet

Publikováno v: Revue Française de Civilisation Britannique, Vol 28, Iss 2 (2023)

On 11 March 2020, the World Health Organisation warned its members and the world that Covid-19 had reached pandemic status and could not be controlled. As a consequence, countries across the world decided to seal off their own borders and implement v

High-power all-fiber ultra-low noise laser

Autor: Zhao, Jian, Guiraud, Germain, Pierre, Christophe, Floissat, Florian, Casanova, Alexis, Hreibi, Ali, Chaibi, Walid, Traynor, Nicholas, Boullet, Johan, Santarelli, Giorgio

High-power ultra-low noise single-mode single-frequency lasers are in great demand for interferometric metrology. Robust, compact all-fiber lasers represent one of the most promising technologies to replace the current laser sources in use based on i

Non-linear amplification to 200 W of an electro-optic frequency comb with GHz tunable repetition rates

Autor: Ye Hanyu, Leroy Florian, Pontagnier Lilia, Santarelli Giorgio, Boullet Johan, Cormier Eric

Publikováno v: EPJ Web of Conferences, Vol 287, p 07025 (2023)

We present a monolithic Yb-doped fiber laser system delivering 200 W average power of femtosecond pulses at tunable GHz repetition rates. The system is based on a GHz electro-optic (EO) frequency comb operating in the nonlinear regime. The EO comb pu

Coherent combining in an Yb doped double core fiber laser

Autor: Boullet, Johan, Sabourdy, David, Desfarges-Berthelemot, Agnès, Kermène, Vincent, Pagnoux, Dominique, Roy, Philippe, Dussardier, Bernard, Blanc, Wilfried

Publikováno v: Optics Letters 30, 15 (2005) pp. 1962-1964

Coherent combining is demonstrated in a clad pumped Yb doped double core fiber laser. A slope efficiency of more than 70 % is achieved with 96 % of the total output power on the fundamental mode of one of the two cores. This high combining efficiency
