Their housing is usually made of ordinary low-quality metal or even plastic. High-power DPSS laser modules generate a lot of heat, which needs to be dissipated by the housing. If the housing is made of inferior materials, the heat from the laser will not be released and will accumulate quickly. The accumulation of this heat will cause the laser diode to burn out, thereby completely destroying the laser. The housings of Viper laser pointers and Hulk portable lasers are made of special metal alloys, which are very effective in heat dissipation and protection of laser diodes. When the 95mW Viper green laser pointer works for 60 seconds, as the laser stays cool, your hand will feel the heat released from the housing.
