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…
Controlling and processing technology of electronic multi-function laser pointer
The intelligent digital interactive flat electronic laser pen can actually perform the top-down startup function on the remote control computer. In an insulating shell, it is successively connected with a pen, an electronic induction handle coil, an electronic induction pen circuit and a feeder. On the other hand: a series of RF transmitters, laser transmitter…
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…
Where is the scary thing about laser weapons?
The United States is now developing a new type of weapon, which is very powerful and can instantly penetrate an aircraft carrier. This guy’s such powerful power makes everyone very nervous. Many people worry that such weapons can instantly penetrate the aircraft carrier. Will it be able to change the mode of future warfare in…
What is the difference between the red laser and infrared of the laser pointer?
The meaning is different. Infrared is an abbreviation of infrared, which is an electromagnetic wave that can realize wireless transmission of data. The laser is another major invention after nuclear energy, computers, and semiconductors since the 20th century. It is called “the fastest knife”, “the most accurate ruler”, and “the brightest light”. The laser is…
I have a magical laser pointer
I have a magical laser pointer. My laser pointer is very delicate. It is silver-white. There are two small buttons on the cap and a searchlight like an elephant’s nose. The laser pointer has many functions. Press the front button to turn it into a flashlight and help at night. I illuminate; press the button…
How does the laser pointer light a match?
Many sellers claimed in the product introduction that the light emitted by the laser pointer can “ignite firecrackers”, “ignite firecrackers”, and even “light cigarettes”. The experimental method is not complicated, and the match is fixed on the table with a dovetail clip. Press the bright laser pointer and aim the laser at the match. Surprising…
What is the difference between laser and LED light
The Laser pointer of laser is different from ordinary light and sunlight. It has physical characteristics such as good directionality, pure color and large energy. In the clinical application of laser, there is a distinction between strong laser and weak laser. The core part of the light-emitting diode is a wafer composed of p-type semiconductor…
What is the difference between a laser pointer and a laser flashlight?
Laser is an attribute. The so-called laser light should be another name for Laser pointer or laser flashlights. Hand-held lasers can be played in your hands. At present, there are two types of external shapes that are recognized: pen type, what you call laser pointer; and another type of flashlight, namely laser flashlight. The laser…
