what is a Laser

With this magazine series, we want to help our members to better understand the topic of "lasers" and to discover together the fantastic world of light.

These journals can be updated at any time and so we ask all our members, friends and partners to support and improve the idea.

Laser Physics

Laser Physics

Thus, an atom with excess energy would spontaneously emit light after some time, at which only the energy is fixed. This changes when it is illuminated with a light wave of the corresponding energy. Then the probability is higher that the atom simply copies the remaining properties of the wave: it then emits light that oscillates with the original in time and spreads in the same direction.
Laser in Dentistry

Laser in Dentistry

Lasers have long been an integral part of innovative dentistry. The devices enable minimally invasive surgery and can create real economic added value. Today, lasers are successfully used in dental practices for the treatment of hard and soft tissue, but also in special fields such as endodontics.
