Tuttavia, Gordon Gould \u00e8 accreditato come la prima persona a usare la parola &quot;laser&quot; e alcuni credono che abbia inventato il primo laser a luce. Gould ha ideato la sua invenzione nel 1958 ma non \u00e8 riuscito a depositare un brevetto fino al 1959; di conseguenza, la sua domanda di brevetto \u00e8 stata respinta e altre societ\u00e0 sono intervenute per sfruttare la tecnologia. (Gould ha finalmente vinto la sua guerra sui brevetti nel 1977.)<\/p>\n<p>In ogni caso, tra il 1959 e il 1960 nacque il laser ottico e una nuova industria attendeva dietro le quinte. Ma cos&#039;\u00e8 esattamente un laser? Il dispositivo stesso non \u00e8 cambiato molto dalla sua invenzione quasi 50 anni fa. Un laser (la variet\u00e0 CO2 cos\u00ec popolare oggi) \u00e8 fondamentalmente un tubo con specchi ad entrambe le estremit\u00e0, riempito con una miscela di gas (il pi\u00f9 delle volte azoto, elio e anidride carbonica). Quando l&#039;energia elettrica viene applicata al tubo pieno di gas, eccita le molecole di gas, che vibrano ed emettono luce che rimbalza avanti e indietro tra i due specchi. Per utilizzare questa energia, una parte della luce pu\u00f2 fuoriuscire da un&#039;estremit\u00e0 del tubo, grazie all&#039;uso di uno specchio semi-trasmissivo, che riflette la maggior parte della luce verso l&#039;altro specchio mentre ne permette la fuoriuscita. Questa piccola porzione di luce passa quindi attraverso una lente dove viene ristretta e focalizzata in un intenso punto di luce o energia laser delle dimensioni di un puntino.<\/p>\n<p>La forma pi\u00f9 comune di laser utilizzata oggi dagli incisori \u00e8 il laser CO2, che utilizza una miscela di anidride carbonica e altri gas per produrre luce infrarossa a onde lunghe. I laser CO2 funzionano bene nell&#039;incisione e nel taglio di materiali che sono cattivi conduttori di calore e\/o elettricit\u00e0 (legno, vetro, plastica, ceramica, gomma ecc.).<\/p>\n<p><strong>North West Rollers ha sfruttato questa tecnologia per produrre un&#039;ampia gamma di manicotti e cilindri incisi al laser da imballaggi flessografici, carte da parati, stampa di sicurezza, rulli di applicazione e arredo, rulli di traino, termosaldatura, spalmatore, rulli Chevron e riavvolgitori, goffratura e anilox in gomma e molti altri.<\/strong><\/p>\n<hr
