What's up guys! This is going to be my first "real" laser build. I have been interested in building a high-powered laser for quite some time, I just never really gave a lot of thought to the concept. Well, here I am now, ready to build one. I've been doing a lot of research online for the past week and stumbled across this forum, and you guys are very helpful and knowledgeable!
Now, this is going to be a somewhat crude design (the appearance will be crude) because I want to be able to easily mix and match different parts in the future, and I also want this design to show all of the working components on the outside for demonstration purposes (mostly for me to learn more).
So take it easy on me guys I am open to lots of suggestions, but I also want to keep this first project under $200 to start off (that's what I told my wife at least, haha). As I get into the mix of things I will definitely increase my budget as needed (or wanted )!
DIODE:
I am really drawn to the blue lasers, I like that color a lot (yeah, I'm a noob, picking a color because it is pretty), but I also really like what I have been hearing about the M140 diode which is 445nm. I was checking out some other 605nm and 510nm diodes, but ultimately decided to go with the 445nm.
Now, I have heard that the M140 is rated for 2 watts, and the guy that runs DTR's Laser Shop has confirmed that the M140 can take 1.8 amps and deliver over 2 watts of optical power very nicely (given sufficient cooling of course). I've heard a lot of good things from you guys about DTR's Laser Shop, so that gives me confidence
LENS:
After way too much time researching these darned lenses, I have decided to go with the G-2 lens. I am going to buy the entire assembly together which inludes the M140 diode in a copper module with leads, and a 405-G-2 glass lens from DTR's.
DRIVER:
I have debated back and forth on building my own driver, which I can do because I have pretty strong background in electronics, soldering, building circuits, etc. but I have been eyeballing these X-drive drivers and they sound really frigging awesome. I'm thinking about getting the Round 16.8mm V6 1.8A X-drive so I can take full advantage of the 1.8 amps that it delivers. Also, I will connect a 12 volt regulated PSU to it, rather than a battery, again for demonstration and testing purposes. I'm not quite ready to go hand-held yet
Anybody think I should build my own or get the X-drive??? Anyone think there is a better driver for under $30 or $40? Let me know! Again, I am way open to suggestions, as this is my first legit laser build.
COOLING:
I am a spaz, so I might do active liquid cooling. I know it sounds crazy but I can rig that up pretty easily. For the body of the laser, I am going to use a solid aluminum block measuring 2x2x6 inches. I will insert the M140 module into a pre-drilled hole of the proper diameter and depth, coating it with thermal compound before insertion for maximum heat conductivity. I will also have several copper or aluminum heat sinks along the body, with the liquid cooling block on top.
SAFETY:
I need goggles but I have no idea where to even start with those.
So that's it, am I missing anything critical? I can use all the help and suggestions I can get. THANKS IN ADVANCE!!!
