Le laser Coherent 430 D3<\/span><\/i>\u00a0est la diode laser la plus complexe jamais con\u00e7ue.<\/span><\/span><\/strong><\/p>\n

Moins de 20 exemplaires ont \u00e9t\u00e9 vendus dans le monde.<\/span><\/p>\n

Ce laser co\u00fbte plus cher qu’une BMW neuve (49\u00a0000 USD).<\/span><\/p>\n

Utilisable en holographie, il poss\u00e8de une longueur de coh\u00e9rence sup\u00e9rieure \u00e0 6 m\u00e8tres.<\/span><\/p>\n

Il utilise une diode laser monomode de 860 nm alimentant une<\/span>
\ncavit\u00e9 de doublage r\u00e9sonante externe. Le cristal de doublage est un KDP deut\u00e9r\u00e9. Son d\u00e9veloppement remonte \u00e0 la fin des ann\u00e9es 1990,<\/span>
\n\u00e0 une \u00e9poque o\u00f9 il n’existait pas de m\u00e9thodes \u00e9conomiques pour g\u00e9n\u00e9rer un laser \u00e0 430 nm.<\/span><\/p>\n<\/div><\/section><\/div>
