Hey All,


1.1W 635nm TK35 Custom Build "ML501P73"

:cool:



Its using the 500mW Mitsubishi ML501P73 diode in it and i love it.:D This diode is Awesome.:beer: It is Running right now at a little less then 1.6A.:drool: It is a very bright laser. Especially in fog.:eg:

Un-like the Mitsubishi 300mW ML520G71 diode which drops off ridiculously fast, this diode is worth the money IMO just for the stability of it. At first i thought we where just going to get more power and thats it. Well we got that + it being Extremely stable & efficient. I can only Imagine what a freak will do.:eek: I don't think this is a freak diode but we will find out once more people start to get these as iam not sure there are any floating around yet but i do know a few members will have there very soon and hope to see some more data on them.:wave:

So I decided to put it in this host the "Fenix TK35". Which I feel in love with when i picked this host up a couple months ago but dint know what to do with it since its not a laser friendly host to work with as the Driver is not connect to the head so i keeped it as a flashlight until now.:eg: The driver is connected to the removable battery holder. WHich is a Problem. I first had wires running from the head down to the driver and battery holder but keeped getting twisted up and i scrapped that idea. I then decided to use it just like it came, which on the head part there was a spring and some metal tabs to make contact with the driver +/-out that would have been going to the LED but now going to my diode. This means that when you unscrew the head from the body the diode is now not connected to the driver anymore.

So Now what i have to do is When I do unscrew the head to change cells out which i don't think im going to have to do too often since the build takes 18650's and i barely left a dent in the capacity after over 30 minutes of use already. I will have to remember to short the driver out to make sure the caps are discharged before i screw everything back together. So its just small detail that i cannot over look. If i do i can most likely kiss this diode goodbye.:( But to make sure i don't forget i wrote a Little sticky to remind me to do so.:wave: The Reason i have to do all this is because i wanted to use the stock Driver>:D I love the modes with it so its why i choose to do it this way.

It would be much easier if i choose to use my X Driver "With the 3 modes option" and fit everything in the head. Which would all fit with extra room left over. But i could not get over the cool pulse modes.:na:


The modes are as Fallow:

Low "pulsed"
Low/Med "pulsed"
Med "pulsed"
High "CW"
Random Strobe "Which is Fast and Slow together"

See video below for LPM test of all Modes and an additional video showing strobe mode and some beams.:D


SO This was a simple build. Just changed the sensing resistor on the driver to give me as close to 1.55A as i could get and connect my diode to it and thats pretty much it. Iam going to run this t this currant for some time nd possible turn it up a little more if i see no signs of the diode degrading.




So here are the Pictures of my build,

This is the Massive heatsink in this build. almost as Big as the one in my F9-009 2W 445nm build. I think it might be as big but a different size. I don't have way to weight it.

LPM Test Long Run::eg:


Beams and Modes:



The Massive heatsink makes it pretty much Unlimited run time but i usually keep it under a few minutes.

It is ridiculously bright Laser. I notice quit a difference from my 900mW build using the 300mW Mitsubishi diode . Even when running it next to my 300mW Mitsubishi 540mW build and running the 500mW Mitsubishi build at ~530mW i notice a brighter beam over the 300mW diode. Probably due to less of shift in WL. I still have not check with my Diffraction Grating how far apart they are but i will shot a video of this soon.:)

Other then the way this hosts setup is iam Very Happy how this build turned out and hope to turn this guy up soon once some more testing is done on it.:)






:thanks: For Looking.!!!




Keep on Lazing.....​

cool man thanks for the loong lpm test run i was curious about that. also LOL the beam looks like a scanned fan :crackup:

good right up :beer:

I was going to make it longer but i figured there was no point. Its very stable and i haven not seen this laser drop more the ~40mW over a long on time of taking those beam shoots.:)

Yes its wide beam due to the lens iam using. Ill take some more beam shots with a different lens and you will see a much better difference. But of course will be less power.

When Holding the laser in your hand and viewing the beam from that point its not as noticeable bad as looking down the other way. But it indeed is very wide beam.!

Nice build as always bro but damn, thats one wide beam!

:thanks: Its a Short Focal length lens which does not clip the sides like the AxiZ lens or the AR coated acrylic does.

This for sure needs correction.

Another great build with a truly unique host.:beer:

1.1W of red. Now we are talking.:eg:
 
Nice host, I see about 15 pictures of it and only one of the heat sink, where is
the other pictures of the insides and how you got it all to go together :thinking:

That's a lot of red :gj:

So if you are worried about killing the LD cuz it disconnects from the driver then
put a bleeder resistor on the out put of the driver this will discharge any
capacitor that could kill your LD, and you can put a cap across the LD's leads also.

WOW! That is one beautiful build. Really amazing work! Now, if only we could get a 1W TEM00 635/650nm Diode...
 
That' thing is gnarly man! :gj:

Make sure you post the difference in power vs the 405-G-1 when you get your 650-G-1 mounted in that bad boy... :D
 
Wow... I am so very jealous right now. Looks like a fantastic laser.

I am curious about the choice of the massive heatsink though. Did you find the 500mW diode to be less efficient and therefore require more heat dissipation?

I'll second this... need to decide whether to order one or not:p

THanks buddy.:) Hope to see a power increase with the 650- G1. Just finished the mount going to test it in a little bit.:)

Stop teasing me.:p I dint do a full tutorial on this build because it was mostly already put together from this thread here:

http://laserpointerforums.com/f50/500mw-mitsubishi-ml501p73-635nm-638nm-diode-69702.html

Ill take it apart and do one and update date the pictures.:) Sorry about that. I know you guys are use to full detail builds from me.:beer:


Never new about the Bleeder resistor. What ohm would you recommend and ill get one on there right now.:) Thanks for the Tip.+1:beer:

I Sure will as i just finished it.:wave: Ill get some results up in a little bit.:)

THe 500mW diodes are very efficent. THe 300mW would drop like crazy no matter how big the heatsink was unless they where very chilled and even then they dropped.

I tried it in a smaller heatsink. It did drop a little more. But nothing like the 300mW diode did.:)

I didn't mean to tease I had not seen your other thread, I've been busy :o

a 50k ohm will drain most any cap and not bother the driver or draw any approachable amount of power ;)

That's awesome, and great news. Based on the three mit$u diode lasers I have, it seems like the 300mW are not that bad when it comes to stability, but at spec as opposed to how they are being run on here.

More stability while they are being pushed hard makes me :yh:

I can't wait until these are more commonly available... although will have to wait after holiday expenses:p

Awesome. Thanks. It will be very easy to add a 1206 50K ohm resistor across the output on the driver.:wave:

I dont have any laying around so i just order some in 50k. I only have 10K ohm 1206 resistors right now.

This will for sure make me much more relaxed.

Thanks for the tip. Its a Good One.:beer: I will keep this in mind when i need it again in the future.
 
Here is a New LPM test of using a 650-G-1 lens from Jayrob.

>>>Check out the 650-G-1 lens Here.!<<<




Nice Power increase.:D The Jumping around in the beginning is due to my shaky hand.

Also I notice a better "Dot" with this lens.:) I think it might be due to the different shape of it. Not sure but i like it.:beer:
