This listing is for one brand new 3.8mm 900mW 405nm single mode laser diode. It was carefully extracted from a brand new 16X BDR-209DBK Blu-ray sled. The driving current must not exceed 700mA but 600mA is recommended to extend the life of the diode. These diodes can reach 1+ Watts. 

Check out my listing for the BlackBuck 3A constant current driver. Perfect for this diode as well as many others.

You must know what you are doing before hooking these up. Reverse polarity, excessive current and high heat will damage or ruin these very quickly. A constant current laser diode driver is required to drive the diode. The current should not exceed 700 milliamps!!! The diodes must be inserted in to a laser diode module w/ heat-sink before energizing to dissipate heat. A glass lens should be used as well. 

I normally ship the same day or before the next available pick-up is available. Once your order is placed it will go out right away because I don't want you to have to wait any longer than you have to. Most orders are delivered within 3 business days in the continental US. International orders take longer of course but they have been getting delivered fairly quickly.


Due to the volatile nature of electronics of this type, returns will only be accepted in original, sealed packaging.

Please don't hesitate to contact me with ANY questions regarding my listing(s). I can offer a lot of technical assistance and/or point you in the right direction to find the answers you are looking for. I am usually very quick to respond and I'm more than happy to help.

I will leave positive feedback once the transaction is complete. Please return the favor!
