Hand-held laser, also known as Portable Laser (Portable Laser), is a small laser that can emit relatively low-power lasers (Laser). The emission principle of the laser and the special process of its generation determine the zero-setting, two-year-old, five-year-old, one-to-one, and a laser with characteristics that ordinary light does not have: three good (good monochromaticity, good coherence, and good directionality. ) One high (high brightness). Using the laser's good directionality and high brightness, it can be widely used in medical care, military, security, counterfeiting, various electric tools, instruments, equipment, locators, laser marking instruments (line casting instruments), and various sheet cutting Forming machines, stone machinery, woodworking machines. This device, called a quantum cascade laser, provides very advanced imaging capabilities and may have an "immediate impact" on applications ranging from detecting cancer cells to identifying explosives.
According to reports, the length of a portable Laser pointer is only a few millimeters, which is thinner than a human hair. Paired with pocket cameras, they can now be operated wherever there is a power outlet—just use a portable laser pointer to keep it at an operating temperature of approximately minus 23 degrees Celsius.
