Very nice build Rich, how do you like the PL450? I thought about doing a build with one but got tied up in a bdr-209 project. I like the look of the skyray host alot as well. I have a heatsink for one but unfortunately don't have a host anymore.:yabbmad:

Hi,
I'd prefer a smaller host if the power is only 200mw. But I might not know about the diode very much. Great build anyways. Just rep'ed. :beer:

Hi,
Thanks J the host fits the diode nice no heat at all i have a few of the hosts. i have some 66 pen hosts and some Husky pens to but figured that i use a larger host .

Very good Rich I think the larger host was a good choice. Keep that diode cool and your stability should be pretty good. Which your graphs show very nicely.

Hi, Jordan..
Thank you for the compliment
@ Cutis,
I thought so to we run the larger diodes in massive heat sinks for cooling. Why not run these great smaller diodes in a larger heat sink also to keep them cool and running correctly . Even a simple 501B would be great to for these little guys..

Precisely, I'd rather a larger host, and a better looked after diode. What about those pocket class 4's. I always think that they deserve more cooling and longer run times than being stuck in a inadequate small heatsinked host. Keep up the good work.

Hi Cutis,
personally i'm not to fond of building these high power diodes in such inadequate heat sinks, ok some think it's cool to put a huge diode in a small package . That diode will never last as long as it should in a larger sink , it's been proven time and again. Thank you were on the same page buddy..

I don't think it is cool. I also think it adds to the danger as well. As a designer, i know a little bit about behavior based instincts when you design products. There is something called an archetype, where you perceive a product based on it standard form. The problem with these compact designs, is that they make class 4's crossover into a lower classes archetype. You usually associate these small pocket lasers with lower powered diodes, and use and store them differently. If someone with less experience was to use the class iv version, they could inadvertently judge the situation wrong based on what they had previously known of that form and shape. As for lifetime, the higher the average diode operating temperature, the shorter the lifetime of the diode. Yes, I definitely agree with you

Hi Curtis,
Well said my friend, I can't see some folks purchasing a high power in a small host such as a pen. The money they spend on it will no last long and the diode will deteriorate and Led or die. Heat is a killer as they over run these diode past there original purpose..

No, at least not experienced people anyway. I now make lab based lasers instead, as it allows them to have better heatsinks or even a fan to assist cooling. This improves the experience also as there is no need for batteries. As long as the cooling is adequate, it also allows for a better duty cycle.

Hi Curtis,
lab builds are the best for running any diode massive sinks and fans can only create a great build. I have a lab build it runs at 675nm to 680nm . stable at 900+ mW's what a wonderful WL deep crimson Red..

Wow, that is a lot of power for 675nm. Every colour calculator I have come across doesn't show a difference of colour between 650 and 700nm. Is there a huge difference between 675nm and 650nm?
