Principle of Solid-State UV Laser Output
The laser must have the above three parts, the pump source , the working material and the optical resonant cavity, and the laser using solid laser material as the working material. The working substance undergoes population inversion distribution under the action of the pump source and becomes an active substance, which has the effect of light amplification. Part of the amplified light is fed back to participate in excitation, and the resonant cavity oscillates, and laser light can be produced after certain conditions are met. 1. Pump source: its function is to give energy to the working substance, and to excite atoms from low energy level to high energy level of external energy. Usually there can be light energy, thermal energy, electric energy, chemical energy, etc. 2. Working substance: At the core of the laser, only the substance that can achieve energy level transition can be used as the working substance of the laser. 3. Optical resonant cavity: make the stimulated radiation of
Red/Green/Blue 3in1 White Laser System
This is a 13W RGB multi wavelength laser system with radiator. It supports CW and modulation. The white laser beam is a laser synthesized by red, green and blue lasers. Each laser has a separate control switch and power adjustment button. Let's check it now.
The Basic Principle of 589nm ALL Solid State Laser
All-solid -state yellow lasers pumped by laser diode are developing quickly, and have great applications in laser medical, space target detection and identification, spectrum, laser display and other fields. At present, allsolid -state yellow lasers at 589nm with high power, high stability, high efficiency and high beam quality are theresearch interest in laser field. The research status and development of all-solid-state yellow lasers at 589nm were summarized and analyzed in this paper, which was useful reference for the future research in this field. Nd:YAG uses Nd3+ as the activated particle, and its main transition energy level diagram and emission cross-section parameters are shown in Figure 1, and Table 1. The Nd3+ particles located at the energy level of the laser will undergo radiation transitions to the three terminal energy levels of 4F9/2, 4F11/2 and 4F13/2 at the emission branch ratio of 0.6:0.25:0.14, emitting 946nm, 1064nm and respectively. 1 319nm fluorescence spect
