The green laser pointer power gradually rise

Check the lens is too dirty or non-destructive loop, the optical path without a serious shift. Need to clean or replace the lens, adjusting the optical path. If the optical path is normal, check the water cycle is normal, intermittent water pumps and pipes clean or replace the pump, if the water cycle, the problem may be water protection fault, water conservation measure conduction is normal or short water protection test. The built-in laser module has improved the heat abstractor of 200mw laser pointer.If you do not normally need to replace water protection 5.6. If the problem persists, motherboards, laser power, laser tubes are likely to lead to this phenomenon than to be interchangeable parts, find out why. If there are laser power, when not using a laser, the laser tube aging, the need to replace the laser tube.
Outside the hole wall surface tension of liquid flow and the parietal cavity continuous with the pore pressure generated by the steam rally and maintain homeostasis. The green laser pointer only contains four buttons but they have all the common functions of a regular green laser pointer.Beam continuously into the holes, holes in a continuous flow of foreign material, with the beam moves, the hole is always in steady-state flow. That is, holes, and the molten metal around the hole wall of the forward speed of the beam with a leading forward, remove the molten metal fills the hole left by the gap and subsequently condensed, so the formation of the weld. 6.2 Factors affecting the impact of the laser deep penetration factors include: laser power, laser beam diameter, material absorption rate, welding speed, shielding gas, lens focal length, focus position, laser beam position, weld start and end points The green laser pointer power gradually rise, gradually decreased control. 6.3 Characteristics of laser deep penetration characteristics and advantages: (1) high aspect ratio. Because the molten metal around the cylindrical steam chamber and extends to the formation of the workpiece, the weld becomes deep and narrow.
The basic principle is divided into the following three steps: First, the role of the pump light at 1117nm, using P2O5 produces frequency shift, get 1312nm Stocks of a component; then in a Stocks role, using the frequency shift of quartz optical fiber get 1375nm secondary Stocks components; Finally, again using the frequency shift of quartz optical fiber, and get 1427.0nm, 1455.0nm and 1480.0nm of the laser output. It should be noted, as far away from the Raman peak, therefore, the interaction between the different Stocks can not be ignored.
