The Results Are Applied To Practice Green Laser Pointer
This green laser pointer result is applied in practice. Although it is not yet possible to remove all 30,000 optical elements. But it is possible to reduce the number of optical components to 300. Realized an order of magnitude leap. "From the perspective of the market, the application of such lasers will greatly reduce capital and labor costs. In the past, when using semiconductor lasers, multi-lens groups were required to perform beam shaping, which was expensive, complicated, and the yield was low. Now it can be solved with a lens The problem is reduced, the technical difficulty and the complexity of the system are reduced, thereby improving the stability and service life of the green laser pointer system.

Due to high luminous brightness and strong convergence ability. Their photonic crystal green laser pointer has a power density several times higher than the original semiconductor laser. Under the same laser power density requirements. If the ordinary laser needs 2 watts of electric power to drive. The laser they developed only needs about 1 watt, that is, only 50% to 60% of the original power is required, and the overall power consumption is reduced. Low power consumption, high stability and small size will bring huge competitive advantages to the overall system. Currently. This low-cost, high-efficiency, low-power semiconductor green laser pointer technology with a series of independent intellectual property rights is being pushed to industrialization. Initially realized the original intention of making semiconductor lasers more “useful”.
