Re: 12x Murder Fund! (Complete!)
yeah, but realistically for the time being it is more likely to be used in lab-style lasers. Also, doesn't wicked lasers use microcontroller-peltier tech in their higher powered lasers? We should find us some round peltier systems...
That was one of the inherent flaws of the Spyder II laser (dunno about spyder III). The peltier would keep the crystals (or diode, dunno what they decided to cool...probably both) cool for a bit of time, but the problem is the sinking.
After a limited amount of time the laser itself would overheat (remember reading long ago some user mention the laser getting HOT quick), due to a lack of thermal mass. The heat itself cannot be radiated fast enough.
When the hot plate of the TEC becomes to hot, the effectiveness of the peltier drops significant, with the "microcontroller" not being able to hold a temperature due to an inherent lack of sinking mass, the stability goes out the window. (Hercules uses active cooling, allowing complete thermal stability over time)
Though these 8X 5,6mm diodes do radiate less heat than a DPSS laser, their need for temperature stability is nowhere near that of a tuned DPSS system.
Another thing to consider is that a peltier is 5-10% efficient and will result in extra heat being dumped into the host (it is not a magical device that teleports heat to a distant black hole), effectively shortening the "duty cycle", very counter-productive.
In our case, limited thermal mass and passive cooling, adding a peltier which would admittedly add a "cool" factor to a host, is not justifiable from an engineering point of view, imo.
BTW: Just read this and the 8X murder thread, AWESOME guys, now this is a community, everyone joining together for the future generations and for knowledge, awesome, everyone who donated to this and the 8X fund, thank you. (BTW You can count on me on the next murder batch or now if there is another fund somewhere. (haven't been reading too actively
))
