What kind of laser diode does a Casio projector use?
Most of the Casio projectors use a 445nm laser diode that is rated at 1 watt. The projectors have the diodes running at 600mw for life.
What does the nm in 650nm laser diode mean?
"nanometer" or billionths of a meter. 650 nanometers is the wavelength of the light produced by the diode.
What is required to turn a LED into a laser diode?
you can't. they are two different things. however you might be able to focus it to a small point with a lens. It is possible to use an array of hundreds or thousands of high intensity LEDs to pump a dye LASER. But this does not make the LED itself a LASER, just the source of energy for a different type of LASER.
What devices are used for diode?
Your question is not completely clear, but I'm going to guess what you might want. Here is a list of various types of devices that are/were used as diodes:galena (lead sulfide) cat's whisker detectorvacuum tube diodegas filled diodecopper oxide rectifierselenium rectifiercavity magnetron (specially constructed vacuum tube diode that acts as a microwave oscillator)germanium point contact diodegermanium junction diodesilicon junction diodevaractor diode (voltage controlled variable capacitor)zener diode (reverse breakdown regulator)avalanche diode (surge protector, etc.)IMPATT diode (microwave negative resistance amplifier)metal-semiconductor junction (schottky) diodeshockley diode (threshold trigger)photodiode (light sensor)tunnel diode (negative resistance amplifier)various types of light emitting diodesvarious types of LASER diodessilicon solar cellsgallium arsenide solar cellsetc.There are also a wide variety of two terminal devicesthat can be referred to as diodes, but can conduct in either direction:neon lampsneon lights/signscold cathode fluorescent lampsmercury vapor street lightshigh & low pressure sodium vapor street lightsgeiger-mueller tubexenon HID vehicle headlight bulbsgunn diode (microwave negative resistance amplifier)PIN diodeetc.
Which is better light emitting diode or laser diode?
Laser diode
Which is better injection laser diode or light emitting diode?
Laser diode
What is the difference between spontaneous emission of radiation and stimulated emission of radiation?
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
Electronic devices that begin with the letter L?
Laptop LED TV Landline phone Laser printer
What type of laser is a diode laser?
A diode laser. Also, a continuous wave laser.A diode laser. Also, a solid state laser.A diode laser. Also, a high efficiency laser, comparing to other types of laser.It's a semi-conductor laser
What do the acronyms 'LASER' and 'LED' stand for?
LED is "light emitting diode". LASER was originally an acronymn which meant "Light Amplification by Stimulated Emission of Radiation". Easy to see why they'd want to shorten that one.
How does a laser measure work and what are its key components?
A laser measure works by emitting a laser beam to a target and measuring the time it takes for the beam to bounce back. The key components include a laser diode, a sensor, and a microprocessor to calculate the distance based on the time taken for the beam to return.
Is a diode laser a nd. yag laser?
No, a diode laser and an Nd:YAG laser are two different types of lasers. A diode laser uses a diode as the laser medium and is commonly used for various applications such as hair removal and skin treatments. On the other hand, an Nd:YAG laser uses neodymium-doped yttrium aluminum garnet as the laser medium and is often used for medical and cosmetic procedures, as well as in industrial applications.
How many type of diode?
There are many types of diodes that are used for different functions in electronics. The most common types include the laser diodes and the light emitting diodes (LED).
What are semiconductor diode laser describe with energy band diagram the construction and working of a semiconductor diode laser?

What is a super luminescent diode?
With their emission properties Superluminescent Light-Emitting Diodes (SLEDs) are closing the gap between Laser Diodes (LDs) and Light Emitting Diodes (LEDs).They offer the broadband optical spectra of LEDs and the spatial coherence of LDs. Compared to Laser Diodes and LEDs, SLEDs can be understood as • Spatial coherent broadband laser diodes with a beam-like output • Temporal incoherent laser diodes with a broadband spectrum • Speckle-free laser diodes with a short coherence length • Spatial coherent LEDs with a beam-like output
Do they use a laser in an optical mouse?
Yes, that is a laser diode
