How to Make High Power Laser Work for a Long Time?

Image
High-power lasers usually generate large amounts of heat, which can easily damage the laser tube for a long time. It is not recommended to use high-power lasers for a long time. Sometimes, the user needs to make the high-power laser work continuously for a long time. Is there any way? Figure 1. Without heat sink, can not work continuously for a long time We have summarized some experiences in actual work to share with you. 1. Select Laser Ask the merchant if the laser is with TEC when buying. TEC (Thermoelectric Cooler) is a semiconductor refrigeration chip, which is widely used in temperature control in various equipment. Figure 2. Heat sink and fan Laser working at high temperatures will cause damage to the laser tube, so it is also necessary to bring an overheating protection module. When the temperature rises to the limit of the laser tube, the laser must automatically stop working. 2. Do a good job of heat dissipation As long as the heat dissipation is done, t...
