5 watt 470nm custom build

hmmm the 120mw version is $2000 the last time i talk to toptica...... and guess what? wavelength shift to the 490nm+ ......
 





Really, my post didn't save?!?!?!?!? :mad:

Here I go again, ugh:

Your lucky to have 470nm! Many people don't own a 470nm laser, myself included. Only got 473nm :p

One member reported 488nm to play tricks on his eyes. One second it looked cyan, the other greenish. I personally find that 473nm-485nm to be the sweet spot of blue/cyan before heading into greenish territory. I personally don't find the 490nm-505nm range appealing :p

yes that's true... :) very few have seen the 490nm+ range... i think there's only a few of member have had that wavelength in their collection.
 
OK. I have seen 1.2W many times during testing a bdr on a variable DC power supple but I have never been able to build an actual 1W that didn't blow the diode very quickly when actually running off batteries and a driver. I have yet to see anyone posting a video showing a 1W 405nm running for awhile even though there have been some claims that they were over a watt. I've personally blown a minimum of 3 of them and have plenty of experience building with them as I probably have 10 builds with them mostly around 800mW because they haven't blown there.
That diode is very sensitive and it may work well as designed but it should have been bigger than 3.8mm like the 12x is. There's a reason why DTR isnt selling them pushed much. My bet is that diode has been his most complained about and it's a good decision on his part to sell them with a driver set more in line with realistic output goals.
Alien says he blew 3 of them before getting one to survive so keep that in mind;) I have a few ideas of why they blow even though they test out on a power supply and I've posted them a few times before. There is now a specific driver made for this diode as they think it is some kind of unstable frequency issue or ripple thats the issue BUT for now it's only offered in a fixed set 500mA which would greatly increase diode life anyways. I used this driver in a pen build and it output about 700mW if I remember correctly with a G lens. Some diodes can be pushed to 4 or more times their data sheet max and some can't take much. ALWAYS look at testing data and what others are doing to see what is reasonable and ALWAYS be prepared to be let down with a diode blowing and the loss of what you spent. If you can't handle the loss of the cost then don't spend your $ on it;) Like others who like to build I can't imagine how much all those blown diodes I have would be worth if I didn't spend the $ on them. Think I would be in shock.

Yeah i liked the 405nm it was hard letting it go :)
i have one more but its at 450mA am trying to find a adjustable to 1A driver
, did you test the driver i send ! its it 4.5A or 5A or 2.3A :)

Actually that driver tested at a rock solid 955mA;) Gave me something to do cleaning off the epoxy:)
