Different technologies Laser Pointer adopts will make the laser pointer have different functions.
Microsoft and other software process specification of large companies, the number and treatment of software testers and programmers is not much difference in the treatment of outstanding testers even higher even than the programmer. Software testing will become an industry has great prospects for development, software testing promising, the market needs more testers with extensive testing technology and management experience, they are also software experts. The past two years the demand of the domestic software testers is increasing more and more IT companies recognize the importance of software testing, encouraging the status quo and development trend so I have a larger development of China's software industry is re- hope. The customer can know the design or technology of Laser Pointer in advance.
However, the current status quo is: on the one hand more and more test engineers demand for high quality and the greater the other hand, the original test engineer's career is not enough emphasis, many people do not understand the test engineers specifically what kind of work . This makes a lot of IT companies can only filter through in the actual work out of the way the test engineer, domestic short-term will be a serious shortage of test engineers. According to the understanding of the recent online recruiting IT talent, many enterprises are currently recruiting a software test engineer are rarely able to hire the right people smoothly at the fair. In a specific course of their work.
Can also be used to pulse the light source to illuminate the work of media, known as the optical excitation; thermal excitation, chemical excitation. A variety of incentives is vividly called the pump or pumped. In order to continue to be the laser output, we must continue to "pump" in order to maintain more than the next level in the upper level the number of particles. With the right material and the excitation source, to achieve population inversion produced by the shock radiation intensity is very weak, unable to practical application. So people thought the zoom with an optical resonant cavity. The so-called optical resonator, actually both ends of the laser, face to face on two high reflectivity mirrors. An almost total reflection, a light most of the reflection, a small amount of transmission out so that the laser injection through this mirror.
