Blu Ray Laser Diode Driver

200mw 1100mw red green blue ir laser diode power driver circuit 5v w ttl parameters wavelength 200nm 1100nm working voltage 5vdc working current 250ma.

Blu ray laser diode driver.

A dvd writer has a red diode with a wavelength of 650 nanometers nm. The diodes are professionally extracted from replacement sleds for the bdr 209 blu ray disk burners so the pins will be a few mm shorter than a diode direct from. These are connected in a ccc common cathode can configuration. A blu ray writer has a blue diode with a wavelength of 405 nm.

The blu ray diode is pretty easy to locate. The case is the cathode ve of all three laser diodes as well as the monitor photodiode. After you have removed the laser mount you need to scrap away the remaining glue and using a small jewelers screwdriver gently i mean gently tap around the edge of the diode housing to free it from the mount. Look for a unit with a writing speed of 16x or faster.

Obtain an old dvd or blu ray writer. These units have diodes with a power output of 150 milliwatts mw or better. All modules are tested and are in working condition prior to shipping. The laser diode can actually contains three laser diodes emitting at 780 660 and 405 nm for cd dvd and blu ray respectively.

How to make a high power burning blueray laser. I do offer a boost laser driver that is capable of driving this diode off a single li ion see my other offerings. This step up driver board works from 3 5v input and steps up the output voltage to suit 405nm blu ray laser diodes. Now onto the first pic.

There are 2 screws to remove and a small ribbon cable that needs to be cut off. It is a hybrid part having an interface compatible with a conventional ldd but an internal architecture similar to a write strategy ldd. Drive current is set with a variable pot on the driver board.
