Well almost!
I've just ordered a diode from daguin.
and a boat load of other stuff off ebay, including:
A heatsink designed to fit the aixiz module
The aixiz 405-455 glass lens
A switching 5 volt power supply (2 amperes) (one of those metal box with holes all over types)
A nice aluminium project box with flanges to help with mounting in the projector/harp
I have yet to order a flexmod P3 (the driver). Its got everything I need (analogue/TTL, interlock saftey, 7 second delay etc). I will buy this tomorrow.
I went with an alu box as although its harder to machine/drill, it will become a giant additional heatsink.
I will be documenting my build here. I am going for a lab laser design which will be either running in a scanner or be the heart of a laser harp.
I NEED GOGGLES for this thing. These diodes can go to insane power levels (well for me anyway, I dont dare fire up my 1 w green without laser glasses on!). Suggestions would be welcome. I'm gonna need 2 pairs, one for me and one for my mate who'll be working with me, or in close proximity to the laser.
I'm also thinking its about time I invested in a power meter, so off to investigate those shortly. I'll be getting one around the same time I get some goggles for the eyeballs. No I wont be even *THINKING* of firing the laser up until I have the laser glasses. (I already have the wicked laser glasses, but apparently these are crap and dont cover the wavelength anyway).
Until I get my power meter I will be setting up my diode at a conservative 600ma, I know some of you guys run em at an amp, but I'm not going to do that without an LPM. Dead on 1 Watt will be sufficient for my needs, and I'll set up the current once I have an LPM. For now if 600ma gives me only 500 mw, I'll be happy with that.
Question: is the blue lasorb laser protector suitable for the 445's or is it only really designed for the blu-ray diodes?
Question 2: my current meter (yes I have a NICE BLUE LED current meter to go on this thing) uses a 0.1R shunt resistor. There is no harm in putting this shunt in series with the diode so I can monitor current right?
Question 3: I've forgotten some basic electronics. I want a 0-5 adjustable signal (to drive the analogue modulation, so I can go from low (SAFE) power level to high once the laser is aligned in the equipment. I've forgotten how to do this except it requires a pot and a couple of resistors.
Anyhoo, look forward to getting my parts and assembling the laser, and will keep you guys updated as parts roll in and the build commences.
edit: looks like my power supply may be a bit low on the voltage side. Since the supple was purchased to fit inside my enclosure, and a e.g. 12V one wont fit, I've found an LM2577 2.5A boost converter on ebay to fix that problem.
