L'invenzione del laser, che ha inventato laser?

Al giorno d'oggi, il laser è utilizzato in molte aree, dalla salute alla tecnologia, dai militari all'intrattenimento alla vita. Il primo laser ottico di lavoro è stato realizzato da Theodore Maiman nel 1960, ma la storia della scoperta del laser è iniziata con Albert Einstein all'inizio del 1900 anni.

 

Il laser è un'abbreviazione usata per l'inglese (amplificazione chiara da emissione stimolata di radiazione). Basicamente, il laser è basato sui fotoni di luce formati dalle transizioni dell'elettrone fra i livelli di energia atomici o molecolari. Si tratta di un dispositivo che produce luce attraverso le emissioni evocate. Nel 1917, Albert Einstein suggerì una teoria delle emissioni stimolata all'indietro.

 

Concetto del Maser

Nel 1958, Charles Townes e Arthur Schawlow Maser (abbreviazione di amplificazione a microonde mediante emissione di radiazioni stimolate) ho sviluppato. Maser mantiene un posto molto importante nello sviluppo del laser. Maser è stato utilizzato per rafforzare i segnali radio in esplorazione dello spazio.

 

Primo laser

Due anni dopo la scoperta di Maser, Theodore Maiman creò il primo laser nel 1960. Tuttavia, Gordon Gould è stata la prima persona ad usare la parola laser nel 1957.

 

Nel 1957 fu inventato da Gordon Gould per il laser ottico, ma non fu un progetto di grande successo per ottenere brevetti. Gordon Gould ha ricevuto un brevetto per il laser che ha inventato nel 1977. Di conseguenza, la dimostrazione del laser di Theodore Maiman è considerare come il primo laser riuscito.

 

Nel 1960 ha inventato Ali Javan gas laser. Ciò è il primo uso di cambiamento di energia elettrica nella storia del laser. Nel 1962 seguì la scoperta del laser a semiconduttore da Robert Hall. Due anni più tardi, l'invenzione di Kumar Patel, laser biossido di carbonio, e Hal Walker telemetria è arrivato.

 

Trattamento oculare con laser

Dr. Steven Trokel inventato un dispositivo laser a eccimeri negli anni 1970. Tuttavia, lo sviluppo di questo dispositivo con l'uso di trattamenti oculistici con il computer è stato diretto dal team Dr. Steven Trokel nel 1982. Nel 1987, la prima chirurgia dell'occhio del laser è stata effettuata. Da allora, il trattamento degli occhi laser è diventato un trattamento ordinario.

 

Torrette e applicazioni del laser

Dal 1960, il laser si è evoluto con studi di miglioramento continuo, invenzioni e applicazioni. L'uso del laser che comincia con il trattamento dell'occhio ora è prevalente in altri settori pure. È usato in tutti i dispositivi elettronici pratici. È utilizzato in molte applicazioni e la ricerca scientifica in strutture mediche.

 

I laser sono utilizzati anche per fare spettacoli di luce in concerti o Club. La stampa laser è diventata abbastanza comune. la spettroscopia, le misure elettro-ottiche e la microsezionazione utilizzano anche la tecnologia laser. In odontoiatria, gli interventi chirurgici, saldatura e sistemi di difesa missilistico beneficiano di questa tecnologia.

 

Dal momento che l'invenzione del dispositivo laser, gli scienziati si sono chiesti dove può essere utilizzato e ha fatto un sacco di ricerca. Realizzato con questa ricerca, sviluppo e invenzioni, il laser è diventato una parte inestimabile della società moderna.
