A manufacturing method of an up-conversion laser pointer, which comprises: a front-end infrared up-conversion fluorescent glass lens (1), a middle infrared 980nm semiconductor laser (2), a metal heat pipe (3) for fixing them, and a 3V battery power supply (4) holder constitute. When the power is turned on, the semiconductor laser emits an invisible 980nm infrared laser, which is converted and focused by an up-conversion fluorescent glass lens to emit a visible laser beam. A portable Green laser pointer with simple structure and high luminous efficiency is manufactured, which can emit visible green light and blue light. Using up-conversion fluorescence technology to directly convert the invisible light emitted by a simple and inexpensive near-infrared semiconductor laser into visible light is one of the methods that people seek. The prior art mainly prepares up-conversion fluorescent glass into a conversion cavity with an optical fiber or rod-like structure, which is repeatedly focused by a glass lens to produce a visible light beam; when the up-conversion fluorescent glass with an optical fiber or rod-like structure is excited by an infrared laser, the transparency is high and the propagation distance is high. Far, but the intensity of luminescence and conversion is relatively weak.

The semiconductor Laser pointer that emits visible light is widely used in the fields of laser pointer, lighting, and performance because of its small size, light weight, and bright colors. The basic materials used in existing products are mostly AlInGaAS, GaN, and ZnSe. The production process is complex, such as: vapor phase epitaxy (VPE), molecular beam epitaxy (MBE), MOCVD method (metal organic compound vapor deposition), chemical beam CBE and other technologies, the above methods are costly and require high equipment and technology. A method for manufacturing an up-conversion laser pointer, using a silicate up-conversion glass focusing lens, combined with a 980 infrared semiconductor laser, to create a portable laser pointer with simple structure and high luminous efficiency, which can emit visible green and blue light .
