Lasers half conductive bestselling type of laser in the world. The lasers the first time in the year 1962 were made, and said to be now in the stage that are in many ways comparable with the position of the electronics industry about 25 years ago. The main force behind this progress, the rapid growth of the telecom industry. but the data storage (read/write CD, password, A-Rod), etc. refers to the round (the markers, laser), and applications of machine work is also the importance of growing have been developed.

in the past few years lasers to the ability to output higher, the dimensions smaller, higher performance, trust, vulnerability, more, and all these are more important to cover the length of the wave wider than the IR of the middle to the end of the blue spectrum, electromagnetism, etc. have been achieved. For decades, etc. achieve the light sources monochromatic stitch coherent, easy operation, and cheap of the IR middle, UV, etc. set a goal for specialists nose. Apart from the spectroscopy, conventional absorption and ., the Raman spectroscopy and oval validation is also of lasers as light sources, coherent states have benefited.

lately, professionals, range, techniques with high sensitivity like the range of the nose within the cavity with lasers have combined. In the spectrum of the nose, stem, etc., application of resources, new laser to determine the structure of free radicals, or species clusters, odd is leading. To, the members, atmospheric, etc. lasers room temperature, which on 8 to 13μM publish. progress fundamental to the improvement of air quality.

in medicine, the application of lasers in the cross-section of journalism, the optical and in the non-injectable blood, for example, predict the blood glucose level, diagnosis, medical, the revolutionary face. In industry, sensors, chemical cheap price in control process, importance has been, for control, in place of the processes of combustion, etc. revealing the waste gas at the point of discharge, and quality control in the pharmaceutical and food industry lasers also another are that for the size of the creation, flow, counting, and measuring the dimensions of particles .
