I have ordered a 30mw 685nm diode off ebay. I am looking for an easy way to make it into a laser. Is there a cheap 650nm laser where I can just swap the 650 with the 685 diode easily? I'm a am new to this and I'd rather not build a whole laser one piece at a time.

Hi this is my first post but I have been lurking for a while now. I am thinking of getting this laser. 50mW 450nm laser pen /single mode/round dot [OL-450-50P] - $82.00 : Zen Cart!, The Art of E-commerce Does anyone have it and know if it works. I have heard that the 450 diodes are unstable...
