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.
The Abrevation for a light emmiting diode is LED.
"Nick Holonyak, 75, invented the LED (light emitting diode) in the 1960s."
LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.
light emitting diode
No, there will be no light emitted from the diode if it is burned out.
ets see the comparison of LED Diode vs LASER Diode.LED Diode :-Full form of LED- light emitting diode.-LED's are small in size, longer life, reliable and require little power.-Here generation photon by spontaneous emittion.-LED's produce a divergent and incohrent light beam.-Types of LED 1> surface emitter and 2> Edge emitter.-Their response is fast.-A wide range of wavelengths is available.-The cost of LED would be less.-An intensity of generating light is less.-Coupling efficiency of LED with fiber is less.-LED's use with the multimode fibers.-Bandwidth of led is moderate.-In led have require no extra circuit because of its simple circuit.-Here require drive current is 50 to 100mA.LASER Diode :-Full form of LASER - light emplification by stimulated emmition of radiation.-Laser's are bigger in size, longer life, less reliable and require more power then LED.-Here generating photon by stimulated emittion.-Laser produce q monochromatic and coherent light beam.-Types of Laser 1> semiconductor laser and 2> Gas laser.-Their response is faster than LED.-A small range of wavelength is available.-The cost of Laser would be higher.-Coupling efficiency of Laser with fiber is higher.-Laser use with both single mode and multi mode fibers.-Bandwidth of laser is higher.-In laser have require extra circuit for isolation of temperature reaction.-Here require drive current is Therashold current 5 to 40mA.
with a simple led and photo diode
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.
This type of smoke detector is more sensitive. It uses a laser diode in the sensor instead of an LED which allows it to be much more sensitive.
Light Emitting Diode - LED
no
It is considered a diode, a Light Emitting Diode (LED).
That would be an LED or Light Emitting Diode an LED is a light
Light Emitting DiodeLight-emitting diode - a semiconductor that glows when a voltage is applied
LED stands for Light-Emitting Diode.
No. Unless the LED is specifically a laser, you can not make it focus like a laser by putting it in a housing. A laser produces coherent light, which is why it acts like a beam. A normal LED is not coherent, and you can not make it so. Although you can not make a collimated incoherent light beam able to travel similar distances as a collimated laser beam, you can collimate incoherent light into a beam which would travel some distance with a small amount of divergence.
LED: light emitting diode. It is a diode that emits light when current passes through it
