It was developed by the Japanese researcher Shuji Nakamura. He worked hard for eight years to develop a blue led and two years more to design and execute the long awaited blue laser diode. In making this diode, he used Gallium Nitride crystals. Previously the material Zinc Selenide was used to make this diode. This discovery started an new era in laser technology and solved the long process of R&D of many blue chip companies in developing a diode with shorter but sharp wave length of laser to enhance the better readability of the laser diode.

With the discovery of blue laser, it was possible to create high-end DVD sets and the trilogy of basic three colors was completed. Nowadays the combination of red, blue and green laser is found in the hand held laser pointers. The Blue Laser Pointer is a exclusive and extraordinary article and the purchaser can be the one first worldwide to acquire this new gadget. This is a 473 nanometer lengthy blue laser light and it is sure to surpass all other laser pointers with its overwhelming demand to buy. It is a unique possession, gives exclusivity to the owner.

It is the latest product in laser technology, that is why it is in wild demand now, and it is priced heavily utilizing its craze. The summary of the features of the blue pointer is mentioned below:
