If microscopic particles such as atoms or molecules have a high energy level E2 and a low energy level E 1, and the particle number densities of E2 and E 1 are N2 and N 1, there are three processes: spontaneous emission transition, stimulated emission transition and stimulated absorption transition. Stimulated emission light generated by stimulated emission transition has the same frequency, phase, propagation direction and polarization direction as incident light. So the stimulated emission of a large number of particles excited by the same coherent radiation field is coherent. The probability of stimulated emission transition and stimulated emission absorption transition is proportional to the monochromatic energy density of the incident radiation field.

Combination of light and shadow

The Laser Show is a laser beam controlled by a computer. It is projected into space or screen by a laser scanner through a color synthesis modulator, which can show various special space beam effects and wonderful dynamic, static and three-dimensional graphic effects. Using the principle that light can be reflected, people and light are integrated to achieve the perfect combination of light and shadow. Under the interaction of music, dance and laser, people look like a laser magic show.

Laser dance is a brand-new dance form integrating laser programming, dance creativity and music production. The three are indispensable, and only by integrating them can we truly embody the essence of laser dance. With the dynamic music rhythm, dancers are like magicians in the world of light and shadow. Laser seems to be endowed with the spirituality of life. Sometimes it will move with the shadow, and sometimes people will dance together. Every beam of light is the best prop, or gorgeous, or surprise.

Performance skills

According to the pre-programmed acousto-optic program, the laser machine produces various lasers on the transparent special glass stage, and the dancers perform different interactive dances on this stage according to the change of light. The dance movements of laser dance are mostly similar to street dance, so it has a more avant-garde and modern feeling with the audience.
