Background

Laser-a device capable of emitting laser light, the basic working principle of various lasers is the same except for a free electron laser. The indispensable conditions for generating laser light are population inversion and gain larger than loss, so that the indispensable components in the device are two parts, an excitation (or pumping) source, and a working medium with metastable energy level. The excitation is that the working medium is excited to an excited state after absorbing external energy, and conditions are created for realizing and maintaining population inversion. The excitation modes include optical excitation, electric excitation, chemical excitation, nuclear energy excitation and the like. The working medium has a metastable energy level to dominate the stimulated emission, thereby achieving optical amplification. The common components of the laser include a resonant cavity, but the resonant cavity is not an essential component, and the resonant cavity can enable photons in the cavity to have consistent frequency, phase and running direction, so that the laser has good directivity and coherence. Moreover, it can shorten the length of working substance and adjust the mode of laser by changing the length of resonant cavity, so that the general laser has resonant cavity.

At present, various lasers are widely applied to the fields of military, civil use, scientific research and the like. However, the traditional laser needs to be matched with a worker when in use, and the worker needs to wipe the acting position once when the laser is used once, so that the working efficiency of the worker is reduced; when the laser works in a dark place, workers need to hold the lamp for illumination, and great inconvenience is brought to the work of the workers.
