Basic characteristics of laser
1. Directional luminescence
Ordinary light sources emit light in all directions. In order to make the emitted light spread in one direction, it is necessary to install a certain condensing device on the light source. For example, the headlights and searchlights of automobiles are equipped with reflectors with condensing function, so that the radiated light can be collected and emitted in one direction.
2. Extremely high brightness
Before the invention of laser, the brightness of high-voltage pulsed xenon lamp was the highest among artificial light sources, which was comparable to the brightness of the sun, while the laser brightness of ruby laser could exceed tens of billions of times that of xenon lamp. Because the brightness of laser is extremely high, it can illuminate distant objects.
