    How do I know I much power my diode can take?

    Ok, so.... Can you tell me what's the spec of similar red diodes? How much voltage can I apply on it? To what value of Current should I limit the power source? Sorry for my ignorance, I'm new to this stuff. Thanks!

    How do I know I much power my diode can take?

    Hello, I'm trying to build a DIY laser out of a x22 DVD burner. I got out this diode from SANYO: Sanyo SF-DS18T Laser Diode with heatsink from SFDS18T Optical Pickup Laser Lens How can I tell how much power can this diode take? I'm a student and using a lab power supply, therefore I can...

    How do I focus a laser beam?

    The project is very complicated, the laser is only the final punch. I admit that I should have found this forum weeks ago, I had a long research for information but nothing compares to the knowledge you guys have. Steveo, I've ordered the "much more dangerous" laser about a week ago and I hope...

    How do I focus a laser beam?

    Thanks guys. Unfortunately I'm short in time, I need the laser working in one week which is not enough for purchasing and receiving the aixiz housing. Do you have a more DIY solution for me? Is there something else I can use to focus the laser? One more thing... I also ordered this laser from...

    How do I focus a laser beam?

    Hello, I'm an Electrical Engineering student and my final project is laser related. We're building some kind of a CNC machine that should cut Styrofoam or black foam using a laser beam. I've disassembled a DVD-RW x22 and got this laser diode out: I've found the diode pins and connected it...

    Mark a laser track on a paper

    Thermal fax paper you say... I'll try to get one. If you say you could leave marks on it that exactly what I need. Thanks for the advice of using black foam instead of a white Styrofoam.

    Mark a laser track on a paper

    Will this laser be able to cut / leave marks on a sheet of Styrofoam or a thin card board? One extra high burning power (1000-1500mW) infrared TO-5 9mm laser diode + Gift | eBay Thanks

    Mark a laser track on a paper

    Hello, I'm a student for electrical engineering, doing a final project with laser. The purpose of the project is to cut Styrofoam sheet with laser. I'll probably won't be able to cut anything with my low-cost laser, so my alternative is to mark the laser track on a piece of paper. Is there any...
