A invenção do laser, quem inventou o laser?

Hoje em dia, o laser é usado em muitas áreas, da saúde à tecnologia, dos militares ao entretenimento à vida. O primeiro laser óptico de trabalho foi feito por Theodore Maiman em 1960, mas a história da descoberta do laser começou com Albert Einstein no início dos 1900 anos.

 

O laser é uma abreviatura usada para inglês (amplificação luminosa por emissão estimulada de radiação). Basicamente, o laser é baseado em fótons de luz formado por transições de elétrons entre os níveis de energia atômica ou molecular. É um dispositivo que produz luz através de emissões evocadas. Em 1917, Albert Einstein sugeriu uma teoria de emissão estimulada para trás.

 

Conceito do Maser

Em 1958, Charles Townes e Arthur Schawlow Maser (abreviação de amplificação de microondas por emissão estimulada de radiação) eu desenvolvi. Maser mantém um lugar muito importante no desenvolvimento do laser. Maser foi usado para fortalecer os sinais de rádio na exploração espacial.

 

Primeiro laser

Dois anos após a descoberta de Maser, Theodore Maiman criou o primeiro laser em 1960. No entanto, Gordon Gould foi a primeira pessoa a usar a palavra laser em 1957.

 

Em 1957 foi inventado por Gordon Gould para o laser óptico, mas não foi um projeto muito bem sucedido para obter patentes. Gordon Gould recebeu uma patente para o laser que ele inventou em 1977. Conseqüentemente, a demonstração do laser de Theodore Maiman é considerada como o primeiro laser bem sucedido.

 

Em 1960 ele inventou o laser de gás de ali Javan. Este é o primeiro uso da mudança de energia elétrica na história do laser. Em 1962 ele seguiu a descoberta do laser semicondutor por Robert Hall. Dois anos depois, a invenção de Kumar Patel, laser de dióxido de carbono, e Hal Walker telemetria chegou.

 

Tratamento do olho com laser

O Dr. Steven Trokel inventou um dispositivo laser excimer na década de 1970. No entanto, o desenvolvimento deste dispositivo com o uso de tratamentos oculares com o computador foi dirigido pela equipe do Dr. Steven Trokel em 1982. Em 1987, a primeira cirurgia ocular a laser foi executada. Desde então, o tratamento do olho do laser tornou-se um tratamento ordinário.

 

Torres de laser e aplicações

Desde os anos 1960, o laser evoluiu com estudos de melhoria contínua, invenções e aplicações. O uso do laser que começa com tratamento do olho é agora predominante em outros setores também. É usado em todos os dispositivos eletrônicos práticos. Ele é usado em muitas aplicações e pesquisas científicas em instalações médicas.

 

Os lasers também são usados para fazer shows leves em shows ou clubes. A impressão a laser tornou-se bastante comum. espectroscopia, medidas electro-ópticas e microsecação também utilizam tecnologia laser. Em Odontologia, intervenções cirúrgicas, soldagem e sistemas de defesa de mísseis beneficiam desta tecnologia.

 

Desde a invenção do dispositivo laser, os cientistas têm se perguntado onde ele pode ser usado e tem feito um monte de pesquisa. Feito com esta pesquisa, desenvolvimento e invenções, o laser tornou-se uma parte inestimável da sociedade moderna.
