The Study On Construction Of A Solid-State Rgb Laser

Based on all solid state output coaxial RGB color laser has well developed in display technology of high quality color display. Compared with other display technology, RGB laser display not only has more brightness, but also has more wider color gamut and higher color saturation. This paper introduced a method to design a solid RGB color laser through two aspects of theoretical analysis and experimental verification. The main research contents include the following aspects:According to the three wave frequency optical parametric oscillation principle and nonlinear frequency change theory,deduce the optical parametric oscillation and frequency in the process of simulation, design the best crystal cycle and optimum phase matching temperature. Model RGB color laser coaxial output;According to the determined output wavelength optical parametric oscillation process and nonlinear frequency conversion and frequency process, get the corresponding monochromatic light three stimulate value. According to the spectral power distribution function, the formula to calculate the color coordinates and the wavelength and power, the quasi white light coordinates as well as the required laser power ratio;Using a single frequency laser to doubling1064nm frequency to532nm green laser, analysis of the measurement of the output characteristics of the green beam quality. In the beam quality and linewidth ideal situation, the lack of Q-run lead to insufficient power density can not reach the oscillation threshold. Use Q device LD pumped Nd:YVO4multiplier to generate high-power532nm pump light green as a front end to achieve optical parametric oscillation threshold in the Q-and high-power injection, Record the experimental data and analysis the experimental results.
