Optimistic about the laser pointer display market

The periodically poled lithium niobate (PPLN) crystal can realize high-frequency conversion of frequency doubling, sum frequency and optical parametric oscillation from visible light to mid-infrared light. It is the only one that can provide any light transmission range by designing the periodic structure. A nonlinear optical crystal with a wavelength output.

The difficulty in developing PPLN crystals is mainly reflected in the process. Not only does it need to understand the polarization reversal mechanism, but it also requires precise control of the additional electric field. It is a long time trial and error, and the time cost and the cost of money are both high.

Zhongke Jingchuang focused on the development of PPLN crystal for 13 years, invested more than 20 million yuan in equipment, conducted more than 6,000 experiments, and applied for more than 20 patents. Now its PPLN crystal performance has reached the same level as the international manufacturers, but the cost is lower and the volume is smaller.

Based on the PPLN crystal development technology, Zhongke Jingchuang has developed three product lines – PPLN chip, green laser and WSS grating. Among them, the market size of green laser pointer is large, reaching tens of billions of yuan. In addition to being used for stage lighting, it can also be used in fire search and rescue, drug inspection, atmospheric monitoring and other fields.

Zhongke Jingchuang said that the annual production capacity of its own factory can reach one million pieces, and the yield rate is above 80%. With the application of vertical sinking in the future and horizontal expansion of market customers, it is expected that the turnover will increase in the next year.
