4-pumped solid-state laser cooling and filter system also. Commonly used cooling liquid cooling, gas cooling and conduction cooling, which the liquid is most common. 5 pump inserted between the lamp and filter devices work material filtered pump light in the ultraviolet spectrum. Figure (5-6) elliptical cylinder condenser chamber 5.1.3 output characteristics of a solid-state laser. Pulse laser solid-state laser pulse solid-state lasers in general characteristics of the laser pulse is generated by the oscillation of a series of short irregular pulse (or peak) consisting of various short pulse duration of about (0.1? 1)? m, the shorter the interval between pulses is about (5? 10)? s. So people don’t need to control the

    by facing to the receiver.Pump light stronger, the more the number of short pulses, the peak of its envelope does not increase. (2) the overall efficiency of the conversion efficiency is defined as the laser output and the input pump light power ratio. For CW lasers (with the power of description) and pulse laser (with a description of the energy), respectively, for the new solid-state lasers 1 diode-pumped solid-state laser diode-pumped solid-state laser with the flashlamp-pumped solid state laser has its main advantages compared to the semiconductor laser-pumped solid-state laser structure, shown in Figure (5-7) (a) shows the end-pumped mode and Figure (5-7) (b) shows the side of the pump mode. The controlling distance of

From the 1970s onwards the development of the plate strip solid-state lasers, is working to overcome the material for the heat distribution in a series, such as refractive index and the resulting distribution of stress birefringence and other inherent contradictions of a proposed structure plan , the structure shown in Figure (5-8) below.

He-Ne laser on the structure and mechanism of He-Ne laser excitation can divided into the cavity type, cavity and external cavity type three and a half, as shown in Figure (5-9) below. Figure (5-9) He-Ne laser forms the basic structure of Figure (5-10) with laser-generated part of the atomic energy level diagram of Ne, Ne laser on the atomic level is the 3S and 2S energy levels under laser level is the 3P and 2P levels. 5.2.1 helium - neon (He-Ne) laser (He-Ne) laser 1. He-Ne laser excitation of the structure and mechanism of He-Ne laser is a typical four-level system, the laser and the laser transition lines are part of the atomic energy level diagram of Ne laser three strong lines in which a laser line start-up depends entirely on the dielectric film mirror cavity wavelength selection.
