Best laser pointer for distance
If your dog is addicted to green laser pointer, for his mental health, the best way is to throw this gadget in the trash can and bring him a healthier occupation and activities: take a quiet walk on the lanyard and get along with others People play party games with dogs, smell research, chew objects, etc. In addition, technically speaking, the lasers purchased on the platform are generally below 1 MWh (500 MW Class 3 lasers). It is very safe for the retina (unless you point it at someone’s eye for 3 hours, it will definitely be blind...) Give you an idea that the power of the laser used in nightclubs is 100 to 150 times that of it . As for the cat's troubles about never catching that damn spot of light, it's actually like a fly entering the apartment. For the cat, it is an intruder on its territory, and it must destroy it, (so it will be frustrated when it cannot catch it, or to be precise, it will reappear after the cat catches it. point.

The 20-watt power level oscillator power amplifier optical fiber master control system (MOPA) has a short pulse duration and a pulse length of 4 nanoseconds. Until recently, because users are familiar with advanced laser marking technology, this further refinement can achieve satisfaction with the red laser pointer. One example is the use of low-nanosecond lasers, which are almost entirely black sub-surface polycarbonate markings, which meet the application requirements of minimal surface damage. Another interesting development of this process is the use of polymers for the subsequent welding process of the same nanosecond infrared laser. In this case, vertical integration, manufacturing cost-effective pump diodes, understanding and careful design of nonlinear thresholds can be used. Manufactured a series of flexibly adjustable lasers with a maximum pulse energy of 60 joules. The minimum laser level adjustment power of 150 watts, the pump high powered laser, the same flash pulse length is 10 milliseconds, and the capacity is 15 Joules and 10 Hz. Can a single-mode fiber really generate this 60 Joule pulse energy? Obviously, this question now has a clear answer, but in the real world, some applications actually require this level of pulse energy. Tests have shown that the laser can not only produce many types of low-power applications that require large-diameter nuclear welding, but also cut highly reflective materials a few millimeters thick, such as aluminum and copper.
