Laser Diode Led
Are LED's and Laser's Related in any way?
Just wondering If I could use a spacific LED to make a burning laser, instead of using the default Laser Diode?
Is it possible to make a burning laser using LEDs?
No, you cannot use an LED to make a LASER.
The mechanism behind the operation of a LASER is completely different and much more complicated. Also, the nature of light emitted by a laser is different from that of an LED.
[Laser's light has a single wavelength.]

Study of Laser Diode and Edfa $111.53 This book basically gives the over view about The properties of erbiumdoped fiber amplifier (EDFA) such as gain and noise figure have been studied. By determining the characteristics of the 980nm, 1480nm 1550nm laser sources and ASE (amplified spontaneous emission) at the output of the amplifier used to determine the gain and noise figure of EDFA. This model allows to follow the signal (1550nm), pump (980nm) and ASE as they propagate along the fiber and determine population inversion .The both forward and backward propagation ASE are important in determining the overall gain and noise figure. For the amplification of more than 80 channels the DWDM (Dense Wavelength Division Multiplexing) has required CBand (15251565)nm and LBand (15651610)nm EDFA.We show that a flat gain spectrum can be achieved in the range from 1565 to 1610 nm when the EDF length, pump power and pump configuration are appropriately chosen. Special care must be taken when selecting the EDF length.

How to find out what resistor to use with led's and laser diodes?
^^
Ohm's law is what you need to work out ANY voltage/ current/ resistance problems.
Ohm's basic law is E = IR.
E is voltage in volts;
I is current, in amperes;
R is resistance, in ohms.
To work out a resistance for a LED, you need first, the LED's specifications. You need the operating voltage, and you need the recommended current.
Let's say these were 2.5 volts, and 20 mA.
Now, you need the supply voltage you have.
Let's say that's 9 volts.
You subtract the LED's voltage from the supply voltage, = 6.5 volts here.
This represents the voltage that has to be DROPPED in the resistor.
Now Ohm's Law. You need a transposition of the basic law here, as R is the unknown.
R= E/I will do it.
E is 6.5 volts, I is 20 mA (.020 amperes).
6.5/.020 = 325 ohms. This is the value of resistor required for this example. The nearest standard value is 330 ohms, so that is adequate.
Check wattage! Watt's law is similar to Ohm's; W = EI.
E & I are the same as in Ohms, W is the symbol for watts.
For the example, 6.5 x .020 = 0.13W.
1/2 watt resistors are more than adequate for LED's. 1/4 watt could be used here, but 1/8 watt would be just too small, and could burn out.
Laser diodes use just the same process to work out a resistance.
