Penemuan laser, yang laser?

Saat ini, laser digunakan di banyak bidang, dari kesehatan untuk teknologi, dari militer untuk hiburan untuk hidup. Laser optik bekerja pertama dibuat oleh Theodore Maiman pada tahun 1960, tapi sejarah penemuan Laser dimulai dengan Albert Einstein sejak tahun 1900.

 

Laser adalah singkatan yang digunakan untuk bahasa Inggris (cahaya amplifikasi oleh dirangsang emisi radiasi). Pada dasarnya, laser didasarkan pada foton cahaya yang dibentuk oleh elektron transisi di antara aras energi atom atau molekul. Ini adalahperangkat yang menghasilkan cahaya melalui membangkitkan emisi. Pada tahun 1917, Albert Einstein mengusulkan teori emisi mundur dirangsang.

 

Konsep Maser

Pada tahun 1958, Charles Townes dan Arthur Schawlow maser (singkat untuk microwave amplifikasi oleh dirangsang emisi radiasi) saya mengembangkan. Maser mempertahankan tempat yang sangat penting dalam pengembangan laser. Maser digunakan untuk memperkuat sinyal radio dalam eksplorasi ruang angkasa.

 

Laser pertama

Dua tahun setelah penemuan di Maser, Theodore Maiman membuat laser pertamapada tahun 1960. Namun, Gordon Gould adalah orang pertama yang menggunakanlaser kata pada tahun 1957.

 

Pada tahun 1957 ia diciptakan oleh Gordon Gould optik laser, tapi itu bukan sebuahproyek yang sangat sukses untuk memperoleh paten. Gordon Gould menerima paten untuk laser ia diciptakan pada tahun 1977. Oleh karena itu, demonstrasi laser Theodore Maiman dianggap sebagai laser sukses pertama.

 

Pada tahun 1960 ia menemukan Ali Yawan gas laser. Ini adalah penggunaan energi listrik perubahan dalam Sejarah laser pertama. Pada tahun 1962 ia mengikuti penemuan laser semikonduktor oleh Robert Hall. Dua tahun kemudian, penemuan KumarPatel, karbon dioksida laser dan Hal Walker telemetri telah tiba.

 

Perawatan mata dengan Laser

Dr Steven Trokel menemukan perangkat laser excimer pada tahun 1970. Namun, pengembangan perangkat ini dengan menggunakan perawatan mata dengan komputer diarahkan oleh Dr Steven Trokel tim pada tahun 1982. Pada tahun 1987, operasimata laser pertama dilakukan. Sejak itu, perawatan mata laser telah menjadi pengobatan yang biasa.

 

Menara laser dan aplikasi

Sejak 1960-an, laser telah berkembang dengan perbaikan terus-menerus penelitian,penemuan dan aplikasi. Penggunaan laser dimulai dengan perawatan mata sudah lazim di sektor lain juga. Hal ini digunakan di semua perangkat elektronik yang praktis. Hal ini digunakan dalam banyak aplikasi dan penelitian ilmiah di fasilitas medis.

 

Laser juga digunakan untuk membuat cahaya menunjukkan dalam konser atau klub.Pencetakan laser menjadi sangat umum. spektroskopi, langkah-langkah elektro-optik dan microdissection juga menggunakan teknologi laser. Di kedokteran gigi, intervensi bedah, pengelasan dan sistem pertahanan rudal mendapatkan keuntungan dariteknologi ini.

 

Sejak penemuan perangkat laser, para ilmuwan telah bertanya-tanya mana dapat digunakan dan telah melakukan banyak penelitian. Dibuat dengan ini penelitian, pengembangan, dan penemuan, laser telah menjadi bagian tak ternilai masyarakat modern.
