Hey guys, I really know nothing about these 2 crystals or how they work. All I know is that they can turn an 808nm beam to 535nm which is what I need for a product I am designing. I am wondering if anyone knows of any sources where I would be able to obtain these crystals in bulk and possibly...

Hey guys. I feel like an idiot for posting this because i'm sure it has been posted a million times. I can't seem to find instructions on how to make a testload for my driver. I have a 9mm 445nm diode and the blitzbuck v3.1 driver. The driver is adjustable and I want to set it to 2.3a please...

Hey guys, I am hoping to use this LED to make a really powerful IR remote. So I need to power it with 1.7v @ 2a. Does anyone know of a good driver to accomplish this? Also, I will be using a PICAXE microprocessor to control it. I am wondering if I should have the transistor pulsing the led on...

Hey guys, I am wanting to make a long range remote for my tesla coil. I have tried radio frequency transmitter/receivers but of course the tesla coil interfiers with them so while I would be able to turn the coil on, it wouldnt turn off... So I guess my only other option is IR. I have made an...

hi, i made a typical M140 445nm 2w handheld laser powered by a mohgasm 1.8a driver. for some reason the burning power of the laser seems to be weakening. I know its not the batteries, because I have been using a steady power supply from time to time, and i notice a difference. It could also be...

Hey, I need to charge my cr123a batteries any way possible really quickly because i am leaving for vacation soon and want to use my laser. Unfotunatly my old charger fried. I tried making one before but one of the batteries ended up exploding (literally), so ive come to you guys first this...

Hey, I dont know much about batteries, so i need some help. I have a laser housing which can hold two cr123a batteries (or the lr123a batteries that im using). Unfortunately they only supply a max of 4v (8v together) and i need atleast 9v for my laser to run at 100%. Are there any other...

I made a 2w 445nm laser... what class is it? i need a really fancy, but accurate name for my laser. i think its class 4 laser.. so something like "high intensity class 4 laser" thanks :)

I'm just got my 445nm 2w LD, with het sink and everything. My LIon batteries havent come yet. I'm using the mohgasm linear driver (1.8a) to power it. the driver can have 6-9v input. is it ok to just test my setup with a basic 9v disposable battery?

Im using this 1.8a driver: http://laserpointerforums.com/f39/fs-mohgasm-linear-drivers-68378.html will 2 cr123a's in series work well to power it? they are 1800mah. If they don't supply enough power, does anyone know what my expected power output would be to the diode? im powering a 1.5-2w...

Hey, so this is my first ever laser build, and ive gone all out and gone for a 2w 445nm design. I was wondering if some people with experience uilding these can look over my design and let me know if im missing anything or if anything is wrong with the design. I will be using a 445nm 1.5-2w...

this driver: http://laserpointerforums.com/f39/fs-jib-drivers-1-25a-1-8a-67623.html what is the input voltage range for the 1.8a? im powering a 2w 445nm laser diode. thanks

I have seen lots of expensive drivers on ebay that put out the 1.8A that people want to drive their 445nm 2w laser diodes. However, I have found this pretty inexpensive driver (here) I'm assuming the potentiometer In the picture controls the output current. I'm not sure what the output...

Hello. So I am wanting to build a 1w blue handheld laser. I know I should be doing a lot more research on this forum, and on lasers, but I need to get this project done asap. I will be getting all the parts off ebay. I think I am looking at all the right parts... and the build should go well...

Hello. So I am wanting to build a 1w blue handheld laser. I will be getting all the parts off ebay. I think I am looking at all the right parts... and the build should go well if I use these... but I was just hoping some professionals could help this non-professional decide whether these are the...

Hey I am interested in buying a 2 watt laser diode from somebody. I don't want anything that I can't see (infrared) Is there a such thing as a 2 watt red/blue/ green diode?

Hey i needed help with something. I have a laser (now broken) that was supposed to be a green argon 50mw laser. But when i took it apart, i took off the lense which had some kind of a filter on it. When i took it off and turned on the diode, it was red! But when i put the filter thing back on...
