Background technology
Since laser was 20th century, after atomic energy, computer, semiconductor, the another invention of great significance of the mankind is referred to as
" most fast knife ", " most accurate chi ", " most bright light ".
Just emitted from the atom of component, atom plays pendulum after obtaining energy（Namely
Excited state）, it can launch energy in the form of photon.And laser, exactly it is attracted（Excite）Photon team out
Row, the photons in this photon queue, optical characteristics is the same, and step is extremely consistent.Draw an analogy and be exactly, ordinary light source, such as
The photon that bulb is issued is variant, and meeting all directions are run chaotically, and are not united very much, but the photons in laser are then the hearts
Toward thinking at one, strength is toward making at one, and this causes them to carry all before one, and power is very big, so that, people in the past often called laser
" death ray ".
When existing LASER Excited Fluorescence light source power is very big, huge heat will be sent, is unfavorable for radiating, laser swashs
Fluorescent light source power hour, cannot meet the condition for exciting fluorescence, therefore, the utility model proposes a kind of fiber coupling is big
Power 450nm LASER Excited Fluorescence light sources, to solve the deficiencies in the prior art.
Utility model content
