About some new possibilities of increasing the intrinsic output power of the photon beam: for definite laser active media

subject

description

Producers and users of laser beam equipment have some wishes as: to have economic machines, the machines must be as small and light as possible, the power supply must be also very light and small. All mentioned desires - and other related with them - may be accomplished by an adequate efficiency of laser beam process. As we know, the first laser began with 2% efficiency. In the process of time, the efficiency increased progressive, and in this way was possible after the year 2000 to have laser weapons mounted on jet planes, including the power supply. In a laser system, there are many points where photons are lost. To reduce this losses, we must treat with the utmost care all points of the "chain" where photons could be lost. We mention: the resonance cavity - inside -, the exit from the resonance cavity, the mirrors and lenses and also other related factors. Each improvement in one of the mentioned points could contribute to the general raising of the laser machine efficiency. Authors were concerned first with some possibilities of increasing the intrinsic output of the photon beam, for definite laser active media, by applying some fields inside the resonance cavity. Such fields, characterized by nature, energy, frequency and other parameters could influence positive the efficiency of the photon beam emission.
