this is really cool stuff !!! Just wondering how much all these lasers are costing?? Caan you post prices and vendors by any chance ?Originally Posted by CalmSeasQuest
All of the lasers I own use rechargeable Lithium Ion cells. They are inexpensive and easy to recharge. You can see the batteries and re-charger and the photo below.
This one is still being built. It now looks like the heat syncing might support a 2400mw diode. This would be the most powerful largest single-diode 445nm I have ever seen. It would certainly incinerate any pest with ease.
The results were complete resulting in total annihilation, poof, ceased to exist, a sudden and total going away of the target
I've purchased kits (survivallaser.com) completed lasers (Lazerer.com) and am currently having a custom unit being built with costs ranging from $160~$500+.
The good news is power outputs are increasing and costs are dropping so they will become more affordable over time. The 445nm diodes being used are basically the same laser diodes used in 12X Blue Ray players.

Perhaps the coolest thread I've read in years. Following along with great interest.

Glad to hear CSQ!
Glad to hear CSQ! Would be cool if they were available to rent
Freakn lasers man! Promising yet dangerous to the average user...
I just received the new build today, it LPM'd in at just under 2.4W :D
I haven't had a chance to put this one to work yet, but upon first impression - the workmanship is first class...
The duty cycle for this build is 2 min on / 1 min off which is amazing for a handheld generating this much power. I'll provide more information once I've had a chance to give it a proper test.

I spent about 30 minutes with the new 2.4W 445nm and it is clearly far superior to anything else I've tried.
- The additional power output reduced Xenia to "bubbling blob" status much faster than my next most powerful unit.
- Despite the much higher power, the heat sinking is so massive the duty cycles are longer. Initial use - 3 minutes. Thereafter 2 minutes on / 1 minute off.
- The optics on this laser allow me to better focus the beam endpoint for more effective burning.
Regarding maintaining focus - If the beam endpoint is even slightly out of focus, the power delivered to the target quickly drops off to unusable levels. I have a clip-on tripod attachment that I tried but rarely use. As I'm consistently changing the focal length based on the distance to the target. I've found it easier and faster to make minute adjustments by adjust the laser position closer/further to maintain focus. I've also found that for me, the best way to maintain focus is based on the sound of the target being eviscerated (snap, crackle, pop...) rather than trying to visually see the size of the beam endpoint (especially difficult with the EaglePair glasses.)
I'll work on setting up a video, for now - as many have asked about how handheld lasers are powered, here's a shot of the Li-Ion batteries being recharged after a successful laze session...

OH Boy!! Can't wait to see this puppy in action~LOL.
