If you have a laser pointer?

If you have a laser pointer, what would you use it for? The Laser pointer is a tool with many functions. It has a wide range of uses. And don’t think that there is only one simple type of laser pointer. There are many types of laser pointers. There are many different laser pointers according…

What function can the low-power green laser pointer achieve?

This practical new type has the advantages of simple structure, small volume, reliable characteristics, good beam quality and low productivity (about 1 MW). Crystal composition самоумножен The crystal coating treatment frequency of the crystal is doubled to stage octave frequency doubling. The crystal surface is coated with two transparent faces and promotes absorption light pump,…

Realization of light spot track recognition with laser pointer

The light point channel detection methods due to the constantly changing teaching environment and expanding scope, it to some extent affects the effectiveness of learning. It is therefore recommended to use different techniques in a large-scale teaching environment. The representation on the didactic screen differs from that of the existing technical literature. Entry methods are…

Smart laser pointers are gradually being used by the public

Laser pointers were manufactured in the 1960s. This use of powerful smoke to transfer to the substrate takes about 2-10 minutes, and the hexagonal nanowires can reach 2-10 microns. Nanowires with a diameter of 20 to 150 nm naturally form a laser cavity. The hexagonal cross-section nanowire sample at room temperature was pumped by the…

The manufacturing principle of the magic conversion laser pointer

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…

Laser pointer with retractable function

In addition, for sales staff in certain shopping malls, lecturers at exhibitions, and teaching staff in classrooms, laser pointers are usually required. However, these personnel find it very inconvenient to carry both mobile phones and laser pointers at the same time. Therefore, these people need a device that has both communication and laser pointer or…
