The Worker Should Obey The Working Table Of Green Laser Pointer

The worker should obey the working table of green laser pointer .
CO2 molecules by the laser oscillator - transfer level transition firing, the role of other gases is to improve the conditions of the discharge gas mixture to improve the laser energy conversion efficiency of laser and laser power levels, can be continuously pumped and pulse pumping, continuous pumping of device has reached 100,000 watts output power, pulse pumping device output power as high as 1012 watts. Such a number of molecules with bound excited states, but there is no bound ground state, called the excimer. A typical example of such as KrF rare gas halides, with a large nuclear separation of Kr + F-ions corresponding to state, without the constraints of the corresponding neutral ground state atoms. In the ground state dissociation of these molecules will soon be so excited and ground state population inversion between the automatic form usually used pulsed fast discharge (20-50 ns) to encourage the laser, electron beam excitation can also be used, but its structure is too large studies in spectroscopy is rarely used. The worker is unloading 200mW green Laser Pointer.
The drawing of green laser pointer is one of the inspection items
Helium-neon laser is the first realization of the gas 50mW green laser pointer, came in 1961, China's first such lasers in July 1963, successfully developed. Laser working substance is helium-neon gas mixture, lasing atom is neon, adding helium gas mixture body is used to improve the discharge characteristics. Improve the energy levels of neon atom density inversion, which can improve the laser output power and energy conversion efficiency. CO2 gas laser is a CO2 molecule, helium body, nitrogen and xenon gas mixtures for the body work of the laser material. Some elements, such as XeCl, XeF and F: the ground state is weakly bound, strictly speaking, these molecules can not be called "excimer", but many of their real properties and kinetic mechanism of the excimer is the same, so the known as the excimer. Those bound with a free continuous emission excimer transition, these constraints bound a transition radiation output of excimer can distinguish vibration with rotating structure. Those who really excimer, such as ArF, KrF and KrCl about 0.5% in the center frequency of a cell within a continuous tuning; and those who tied a bound excimer transitions, such as XeF, XeCl dense in its extension between the tuning, but by no means continuous. Because of the high-power excimer lasers and high-energy, so that in the ultraviolet region can become a practical tunable light source. The shoe for the worker in the 100mW green laser pointer workshop is specially made.
The main features of excimer lasers are: (1) excimer is an excited state to form a molecule that life is very short, only the order of 10-8s, the ground state (ie, laser transition to the next level) life very short, about 10-3s, so its characteristics can only be marked by the emergence of radiation to determine the excimer formation. These characteristics correspond to the radiation spectrum of low-lying excited state to the exclusion of state transitions between the ground state, the fluorescence spectrum is a continuous band, which is characteristic of excimer spectrum. (2) As the laser transition energy levels of particles under rapid dissociation. Therefore, laser level is always empty. As long as the existence of molecular excited states, is in inversion state. (3) The excimer laser level is not a defined vibration - rotational levels. Transition is broadband. Therefore, excimer laser can be tuned operation. (4) excimer laser output wavelength was primarily in the ultraviolet to the visible region, with a wave length features. The customer wants to keep the drawing of green laser pointer.
