Résumé
Abstract

Les matériaux lasers polycristallins transparents, ou « céramiques », offrent de nombreux avantages sur ceux élaborés par fusion, notamment des temps de production plus courts, l'accès à des solutions solides permettant la fabrication de matériaux à transition de phase multiple, une très grande homogénéité et la possibilité de définir des profils et des structures avant frittage. La qualité optique des céramiques a beaucoup progressé et de nouveaux matériaux ont été explorés. Le développement des céramiques concentrées Nd :YAG a ouvert la voie à une réduction drastique de la production de chaleur grâce au pompage direct sur le niveau supérieur. Ceci est particulièrement intéressant pour la fabrication de structures composites du fait de faibles coûts de fabrication liés à la production de masse et de délais de production courts, en comparaison du soudage par diffusion conventionnel. Ce travail décrit un laser émettant plus de 300 W en continu, basé sur une micropuce composite monocristal Yb :YAG/céramique YAG pompée par le côté. Nous discutons aussi des développements futurs, en particulier l'adaptation du profil spectral.

Transparent polycrystalline that is ‘ceramic’ laser materials offer numerous advantages over melt growth methods, including faster production times, their solid solution allows the fabrication of multi-phase transition materials that are highly homogeneous and they show the ability to engineer profiles and structures before sintering. Much progress has been made in improving the optical quality of ceramics, as well as exploring new laser materials. Successfully developed concentrated Nd:YAG ceramics has opened the way for drastic heat reduction by pumping directly into the upper laser level. Especially for the composite structure fabrication, it is attractive because of low fabrication costs by mass production and short delivery times compared with conventional diffusion bonding. In this research, we report on $> 300 W$ continuous wave (CW) laser operation in an edge-pumped 300 μm-thick, single crystal Yb:YAG/ceramic YAG composite microchip.
