PHR-803T laser COMPLETE :D

hey everyone today i got my driver in the mail and as soon as i got it i started the build and have great results i set it below 500mA to be safe. AND IT BURNS
sorry but i have a shit host here are some pics:

BEAM SHOTS:

the housing of the laser:

This is a awesome laser i love burning stuff with it ohh by the way do i need a heatsink?

Haha, Nice build!

Well, yes you will need a heatsink if you don't wanna burn out your diode and about the current your running it at, Do you have exact measurments? these diodes are supposed to be run at around 150ma

 

[australialaser]

i only put it on for less that 1 minute so its not urgent to get a heatsink it running around 180mA i turned the pot down now and it have like 5-6 sec to burn

 

[australialaser]

my next project is the 300mW LPC-826 laser im waiting for the driver >.<

 

[LaZeRz]

5-6 seconds to burn? Turn that pot up a tiny bit

Do you have a testload that you can use to measure current?

 

[jimdt7]

When i saw 500mA i :drool:
Make or buy a testload to make sure you wont kill any diodes.(at least from over-current)
Also about the heatsink, it is a MUST. No matter what.

500mA :thinking:

What driver?

 

[bennett326]

actually more like 120ma if you actually gave this 500ma it would be dead.....

anyways congrats on the first build

 

[australialaser]

no guys you understanding wrong i set it below 500mA i said and for the heat sink can i just put it around the aixiz module?

 

[bennett326]

How far below Iirc the led under 200ma

 

[australialaser]

my test load is being shipped it should be here soon

 

[australialaser]

How far below Iirc the led under 200ma

i dont have my test load in guessing roughly around 160-170

 

[australialaser]

i found this heatsink on ebay Cooling Heatsink/ Heat Sink for 12mm Laser Diode Module | eBay can i just slip it on my aixiz module and will it sink heat??

 

[jimdt7]

Its a good one !

Jim

 

[australialaser]

thanks jim im waiting for my host from ebay >.<

PHR's top out at around 120mA. If you drive them past that, they go poof. The fact that yours is still alive means your below that.

100-110mW with a good lens is about all you'll get out of one. They're good 'first builds' since they're dirt cheap, however if you want to 'burn', you'll quickly outgrow it.
