Here are the best laser pointers you can buy
The excitation type of atomic state and the way of energy transfer can work in continuous wave or pulse mode; photolysis type works in pulse mode; purification type works in continuous wave mode. According to the transition mechanism, these laser pointers can be divided into three types. The number of molecules still present is the quantum number of the rotational levels; g is the degeneracy of the energy levels), i.e. there are still population inversion states between the local vibrational levels. At this time, the laser can only emit the high power laser pointer of the P branch transition, and the gain is not as high as that of the total inversion.

20mw laser pointer with particle inversion
The 200mW laser pointer realizes particle number inversion through chemical reaction and has different inversion modes. In the initial stages of the reaction, there tends to be a completely reversed distribution, that is, the number of molecules of high vibrational energy levels of the small products produced by the reaction. Nv+1 has more electrons than the low vibrational level Nv, i.e. there is an overall inversion state between the vibrational levels.
As the molecules collide with each other exchanging energy and radiating cascade transitions, this fully inverted distribution gradually transforms into a partially inverted distribution until the final inversion disappears completely. Furthermore, some green lasers even produce partial inversion distributions from the start. The working range of a 1000mw blue green laser pointer can produce milliwatts (mW). The output can be as low as 1mW or as high as 10000mW. It produces an extremely bright blue single point laser pointer up to 5000 MW. You can even use it to light matches or cigarettes. In addition, it is an interesting and practical product for sky pointing, lighting, display, registration and many other fields. It is small and light, easy to carry.
