How to make a laser pointer from a flashlight?
Due to the limitations of current laser technology, a range of high-power laser devices are still in urgent need worldwide and are in great demand for modern military, scientific and laboratory research. The cool gadget is also popular for recreational activities such as popping balloons, burning plastic and rubber, cutting electrical tape, and even lighting cigarettes. One can always have a very different experience with the exploding and temporary lighting of this superpower gadget. Laser Pointers are very useful in exploring caves. An important use is to determine how water is stratified in caves and passages. This allows researchers to gain insight into air and water flow. By identifying the presence of wet areas, potholers may be able to identify areas most likely to find bats, spiders and other cave life.

Another use of lasers in cave exploration is to examine underground pools and streams. If the water inside the cave is clear, use a laser pointer to illuminate the underwater terrain so that people on the surface can see it. This method is not as effective as putting bright light into the water, but can be done from a distance without entering or contaminating the water. This basic question helped me clearly understand what type of laser I liked. Low-power laser Pointers are often sufficient for presentations, business meetings, education, or short presentations in PowerPoint. In military, astronomy, starry sky observation, rescue, camping and other scientific research use, should choose the high power output of green laser pointer diode, because can use a high power laser pen laser beam laser visualization.
