Laser Diodes How much power does a cd player laser diode need?
i felt like messing around with an old broken cd player i have and i was wondering how much power i would need to light up the laser diode inside, it has three pins and i think the pin out is this

You won't see much light (other than possibly a faint red glow) from a CD player laser as they operate in the near infrared region. The light is dangerous to the eyes anyway.

High Quality Content by WIKIPEDIA articles The Diodes were a Canadian punk/new wave band formed in 1976. They released five albums: Diodes (1977), Released (1979), ActionReaction (1980), Survivors (1982), and Time/Damage Live 1978 (2010). One of the first Toronto bands playing that style of music, The Diodes helped foster the scene in the city. Along with manager Ralph Alfonso, The Diodes opened the first Canadian punk nightclub in 1977, called Crash n Burn, where many of the citys punk bands at that time played. The first band to play the club was The Nerves, on a double bill with The Diodes. The club was closed at the end of the summer of 1977 due to complaints by the Liberal Party of Ontario (the principal tenants of the building).

In this book, I have optimized the growth of n and pGaN films, and high quality InGaN/GaN multiple quantum wells (MQWs) on sapphire (0001) substrate by a low pressure metalorganic chemical vapour deposition and have fabricated high brightness InGaN/GaN MQW lightemitting diodes (LEDs) under optimum conditions. To improve quantum efficiency which is generally poor in the conventional rectangularshaped QWs due to spatial indirect recombination induced by internal piezoelectric field, we proposed a possibility of quantum dot (QD) engineering with triangularshaped band structure in the InGaN/GaN QWs. The structural and optical properties of the InGaN/GaN MQWs with different threading dislocation densities were also investigated. The effects of Sidoped nGaN and Mgdoped pGaN layers on the electrical and optical properties of the InGaN/GaN MQW LEDs were investigated and optimized under various growth parameters.

Organic lightemitting diode (OLED) technology is used in a variety of display applications, ranging from cell phones and MP3 to prototype TVs, and holds great promise for the production of highly efficient largearea light sources and flat panel displays. It has the potential to become a multibilliondollar industry within a few years. The biggest technical challenge for OLEDs is the limited lifetime associated with elevated temperatures and exposure to moisture. The guaranteed hours of operation (15,000 hr) is currently inadequate for most TVs and replacement of LCDs with the 60,000 hr halflife. This book, therefore, investigated the thermalactivated and moistureinduced degradation pathways of small molecule based prototype OLEDs as well as interfacial electronic properties at the nanoscale level through realtime visualization. The results should help shed some lights on improving luminescence efficiency and lifetime of OLEDs, and should be especially useful to professionals in research and development of not only OLED technology but other organic electronics, or anyone else who may be interested in plastic electronics.

Extraction of the laser diode from the "6x" Blu-ray writer GGW-H20L
what do laser diodes run off amps or volts?
sorry in-case its a really stupid question
An amp is a unit of current, and a volt is a measurement of potential different (voltage). Current = charge per unit time, and voltage = energy per unit charge. Voltage and current do not occur independently in any situation that I know of.
