ROHM a mis au point une diode laser infrarouge \u00e0 haut rendement\u00a0 \u00a0et haute puissance de classe 1kW- <\/span><\/h3>\n

La diode laser RLD8BQAB3 – destin\u00e9e aux syst\u00e8mes avanc\u00e9s d’aide \u00e0 la conduite (ADAS) \u00e9quip\u00e9s d’un LiDAR pour la mesure de la distance et la reconnaissance spatiale. La fourniture des \u00e9chantillons concernera les applications grand public et industrielles telles que les drones, les aspirateurs robots, les v\u00e9hicules \u00e0 guidage automatique (AGV) et les robots de service.<\/span><\/p>\n

ROHM a mis au point une technologie brevet\u00e9e exclusive qui permet d’obtenir une \u00e9mission \u00e9troite des lasers, am\u00e9liorant ainsi le LiDAR \u00e0 longue distance et \u00e0 haute pr\u00e9cision, en commen\u00e7ant par la commercialisation de la diode RLD90QZW5 de 25 W en 2019 et de la diode RLD90QZW8 de 120 W \u00e0 haute puissance en 2023. Forts de ces succ\u00e8s, le nouveau produit de type r\u00e9seau 125W 8ch (classe 1kW)\u00a0 r\u00e9pond \u00e0 la demande d’une diode laser \u00e0 haut rendement et \u00e0 haute performance.<\/p>\n

La RLD8BQAB3 est une diode laser infrarouge ultracompacte \u00e0 montage en surface et \u00e0 haut rendement de 125 W \u00d7 8 canaux, destin\u00e9e aux applications qui utilisent des syst\u00e8mes 3D ToF pour mesurer la distance et effectuer la reconnaissance spatiale. La conception optimis\u00e9e comporte 8 zones d’\u00e9mission (chacune d’une largeur de 300 \u00b5m) par \u00e9l\u00e9ment, install\u00e9es sur un sous-montage fix\u00e9 \u00e0 un substrat \u00e0 forte dissipation thermique.<\/p>\n

La surface d’\u00e9mission du bo\u00eetier comprend un capuchon en verre transparent – une premi\u00e8re dans l’industrie pour une diode laser \u00e0 montage en surface – qui \u00e9limine le risque de dispersion de la lumi\u00e8re caus\u00e9 par les rayures lors du d\u00e9coupage en d\u00e9s, qui peut se produire avec les produits encapsul\u00e9s dans de la r\u00e9sine. C’est la garantie d’une haute qualit\u00e9 de faisceau. Chaque zone d’\u00e9mission est c\u00e2bl\u00e9e avec une cathode commune, ce qui permet de s\u00e9lectionner la m\u00e9thode d’irradiation en fonction des besoins de l’application – depuis l’\u00e9mission individuelle qui augmente le nombre de points d’\u00e9mission de lumi\u00e8re jusqu’\u00e0 l’\u00e9mission simultan\u00e9e la plus \u00e9lev\u00e9e jusqu’\u00e0 des puissances de la classe 1kW.<\/p>\n

\"\"<\/p>\n

Le nouveau produit conserve les principales caract\u00e9ristiques des diodes laser conventionnelles de ROHM, notamment une intensit\u00e9 d’\u00e9mission uniforme sur toute la largeur d’\u00e9mission et une faible d\u00e9pendance \u00e0 la temp\u00e9rature de la longueur d’onde de 0,1nm\/\u00b0C (contre 0,26 \u00e0 0,28nm\/\u00b0C pour les produits standard). En outre, la configuration en r\u00e9seau restreint les r\u00e9gions d’intensit\u00e9 d’\u00e9mission moindre entre les canaux, tandis que le filtre passe-bande minimise les effets du bruit de la lumi\u00e8re ambiante provenant du soleil et d’autres sources, ce qui contribue \u00e0 la d\u00e9tection \u00e0 longue distance et \u00e0 la haute d\u00e9finition du LiDAR.<\/p>\n
