What is the typical heat dissipated by the listed DPSS lasers? How is the unwanted heat removed?
A11: Heat is generated in all laser sources. In most low power red and IR lasers, the generated heat is not significant and therefore do not raise any concern. Basically when operated the case temperature of laser head must remain below 45 °C. Most of our DPSS laser systems have built-in automatic shut down switch that switches off laser if case temperature reaches 45 °C. Higher power DPSS laser systems are shipped with fanned heat sink unit that allows heat dissipation of laser head. For the blue laser modules that are most sensitive to heat, not only heat has to be dissipated effectively, the temperature has to remain at or near the laser’s optimum case temperature (predefined, see Q. 6). Although our blue laser modules come with adequate heat sink a small remote fan is included as well. By placing the remote fan near the laser head, laser may dissipate the generated heat more effectively and operate at or near its optimum temperature. Q12. What is the mode structure of the listed DP
