In 1960, the Hughes research laboratory, Theodore Maiman designed and built a small burning laser generator. He created the first beam of laser, and the laser era was thus open, and people's lives are closely related.

Development of Laser-From X-ray Laser Weapons to Fusion Energy

With the birth of the laser, military institutions and novelists brought a ray gun to reality and began to build a laser weapon. In 1964, 007 movie, Alric threat James Bond with a laser and sawed him in half, which at the time pure fantasy.

The laser has been used widely since created for 50 years. Today, the high powered laser has become the foundation of optical fiber network, and help people to find new clean energy.Let's talk about the development of the laser from birth to applied to all fields of occasions.
Maiman's experiments showed that the flash emitted can charge Ruby rod, and release these energy followed by pure red light pulse form.These coherent light has a constant phase difference which is like soldiers

At first, the color of the Laser Sight was quite limited: Only Ne laser and ruby red can produce a visable ray, and the other lasers produced invisible infrared rays. People created a rainbow colorful laser by a high-voltage discharge krypton laser. Argon can produce blue and green light, krypton produced several other colors, mixing of the two gases can produce the colors of the visible spectrum. Since then, dream laser show was born.The United States use a red He Ne laser bar code scanning gun to achieve automated collection which marks laser technology has been bring into daily life. Zhores Alferov and Herbert Kramer improved the semiconductor diode laser, let the laser really everywhere. The two scientists won the Nobel prize for physics in 2000. Nowadays, such chips can be seen everywhere, such as CD player, Blu ray player, red laser pointer.

Widly Applications

In 1948, scientists invented the holographic technology in order to improve the resolution of the electron microscope, but Emmett Leith and Juris upatnieks invented the first 3D image machine that does not require special glasses in 1964.Since then the use of 300mw Green Laser has become.They recorded the split laser beam on a photographic plate where a beam of light was first reflected off the object, and then joined together with the other beam. Using a laser beam with the same direction will produce a realistic 3D image in the eyes of the viewer.

The first successful application of laser in medicine is to have an intraocular surgery, which requires no incision. As early as 1962, a ruby laser cure a patient's eye, so that he restored vision.Greater success coming in 1968, the Bell Labs engineers using argon ion laser destruction of abnormal blood vessels, in order to avoid the spread of these blood vessels in the retina.This treatment has saved millions of people's eyesight. Now, the laser is also used in cutting the cornea, corrected visual acuity, or remove the birthmark and tattoos.
