Supervising the manufacturing area of green laser pointer

Under high pressure, conductive ionized gas molecules in the discharge process, the gas molecules and electrons accelerated by the electric field collision, the absorption transition to the high-energy electron energy-level inversion to form particles. Reduction compared with the optical excitation electro-optical conversion part, excitation efficiency can be improved. High-temperature heating so that the number of gas particles on the energy level increased, and then suddenly reduce the gas temperature, high and low energy levels due to the thermal relaxation time is the number of particles of different subjects to achieve reversal. Is to use the chemical energy released during the reaction set up to encourage particle inversion. The quality group of green laser pointer is in charge of the quality assurance of led flash light.
Released by nuclear fission reactions of energetic particles, radiation, or fission fragments and other substances to encourage work. Laser beam in the spherical cavity by coaxial multiple-entry, if the position is still close to the beam axis, the optical resonator stability; if the specular beam lateral escape from the cavity mirrors, the cavity is unstable. Ranging from the radius of curvature spherical mirror laser resonator consisting of a periodic sequence of optical components, a typical example, can be divided into two kinds of stable and unstable. The stability of the sequence, the beam propagation is bounded propagation matrix of the matrix elements to take a limited number of real time, near-axis light in the cavity round-trip times, would not escape the cavity horizontal. Sequence of instability, equation into a hyperbolic trigonometric functions, indicating that the beam through the optical components will be more divergent sequences, the beam will escape optical resonator, the beam is unbounded. The fault status of green laser pointer is the important reference index.
Stable cavity: when the spherical optical resonator geometry parameters satisfy 0 <g1 g2 <1, in the cavity of the paraxial rays from infinitely many times and not by the transverse escape cavity, that is, no loss of deflection geometry, the resonant cavity energy loss in the stability of the lowest state, called the stable cavity. As the cavity fundamental mode beam with a Gaussian distribution, it is also known as the Gaussian beam cavity. Unstable resonator: When g1g2 <0, g1g2> 1, the on xn = AnX0 + Bnθ0, θn = CnX0 + Dnθ0, there is an exponential function solutions, as n increases, xn increases exponentially, which means light in the cavity within a limited time after the horizontal spread from escaping the cavity geometry with a larger deflection loss is called unstable resonator. The parameter in the drawing of green laser pointer has to be renewed as per the real situation.
As the cavity if the beam is unstable resonator, like a pair of conjugate points issued, it is also known as point of the beam chamber. Critical cavity: When g1g2 = 0,1 spherical cavity of the coaxial cavity is critical, in addition to confocal cavity, such near-resonant cavity light axis infinitely many times from some and not by the transverse escape chamber, but also part of the light propagation in the cavity from the limited time after the escape cavity horizontal. Critical cavity losses are higher than the geometric stability of unstable resonator cavity is lower than the energy loss between stable and unstable resonator cavities between the geometric parameters for the two types of cavity boundary, called the critical cavity (metastable cavity). Laser according to the process of its formation and the formation of laser work involved in the laser material (activated-ion) energy levels structural features can be divided into. The director of green laser pointer workshop is supervising the manufacturing area of green laser pointer.
Three-level system work material and four-level system work material. Where the ground state and the laser level coincidence or E1-E0. referred to as four-level system. Ruby is a three-level system; Nd3 +: YAG, neodymium glass, molecular nitrogen, carbon dioxide, argon ion, helium-cadmium, and other laser devices are four-level system. Operation of the laser material working process, that a large number of particles of transition radiation process. Laser working transition radiation material in accordance with the frequency distribution of light energy to follow certain rules, and different physical structure of the radiation law is different. The factory inspection and acceptance personnel should sign the report of green laser pointer if green laser pointer is qualified.
