What laser diode is in a dvd burner

\$\begingroup\$ Also, keep in mind that for most diode lasers the frequency is proportional to the current, DVD-R lasers (the actual burner laser) is around 250mw, overdriving with 1w, even if pulsed, will probably cause it to go into some unstable regime and lose all coherence (if it doesn't explode). Additionally, what you are burning needs

Extracting a Laser Diode Driver from a DVD Burner

I got question someone here may be able to answer for me. I just ran across an auction on ebay where someone is sellin the internals for a DVD burner claiming that you can use the burning laser diode to get a 100mw laser. If thats true can you take that diode and add on optics and a power supply to make yourself a nice high powered 650nm laser? An Inexpensive Laser That You Can Build (Read More) This spec indicates that the diode is of a high output. Using older drives will usually result in a lower output and/or shorter diode life. In this DVD burner, the laser diodes are not covered with a glass window so the actual semiconductor crystal is exposed to the environment, therefore an airtight enclosure is required. Sam's Laser FAQ - Diode Lasers Very high power diode lasers using arrays of laser diodes or laser diode bars with power output of WATTs or greater may cost 10s of thousands of dollars! Laser Diode Construction A rough diagram of a laser diode of the type found in a laser pointer or CD player is shown below. This is in no way to scale.

This is the second post about my experiments with laser diodes, you can read the first one here. In this post I cover adding a lens to focus the beam and protect the diode, building a suitable power supply to drive the laser without destroying it, and finally putting the whole assembly in a safe to use mounting frame. Removing a laser diode from a DVD - YouTube Removing a laser diode from a DVD As the semiconductor laser technology advances more and more devices using laser diodes appear.
