The question seems to imply that ever since Creation there has always been
a grand cosmic role for the laser diode, and that once our species attained
the ability to invent it, it was then Mankind's holy mission to sally forth and
find its function.
I think it was more like: Once the purification and doping of solid-state materials
had progressed to the point where a diode could be fabricated out of a couple of
pancakes of them, AND someone over in a different lab had succeeded in getting
a laser out of a roomful of flashtubes and a piece of ruby the size of a pencil,
somebody else ... in a job where he didn't have to worry about purpose, profit,
or function but he could get paid to just come in every day and play around with
stuff, maybe at the old Bell Labs ... read about both of those, and figured out
a way to combine them, doping and joining a couple of pure stones in just
the right way that when he connected it to a battery, it would have diode
characteristics AND would lase! And then, he showed it to his boss, wrote and
published report about how he did it, built a few to demonstrate at cocktail
parties and Physics conferences, and went on to play with something else,
while we ... me and the other bottom feeders called engineers ... thought up
neat things to do with the laser diode.
We built the cool laser pointers, that you could hang on your key-chain, put
a red spot on the screen during your high school presentations, do optical
experiments with, and give your cat some great exercise chasing the red spot
on the floor. We built laser diodes and detectors to create and detect microscopic
pits on a high-polished plastic surface, small enough fit into a machine that could
fit in your backpack, run on a couple of skinny batteries, and hold a plastic disk
with an hour of music 'burned' on it. We put laser diodes and detectors into your
computer mouse, that can detect textures so tiny that you can use a sheet of
white paper for a mouse-pad, and we got rid of the clunky potentiometers and
wheels inside the mouse, that used to pick up hair and gunk and get jammed
every couple of months.
But probably the most important bright idea we had that takes advantage of the
laser diode was the method we designed to efficiently couple the light from the
diode into one end of a glass fiber ... the width of a hair and miles long ... and
detect it at the other end. From there, it was a piece o' cake to 'modulate' the
output of the diode, detect the variations at the other end, and kick off the
whole modern fiber phenomenon, that now carries trillions of bits of data
over a single fiber every second. This, at last, solved the cosmic background
requirement that lay unfulfilled since Creation, when finally, subscribers are able
to satisfy their crying need and fundamental human right to stream a different
movie into each room in the house while recording three more to watch later in
case they ever feel like it. Or to have the choice of 300 channels when they plop
down at the TV, even though there's STILL nothing on.
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.
Using a diode laser bar for hair removal treatments offers advantages such as precise targeting of hair follicles, faster treatment times, and reduced risk of skin damage compared to other types of lasers.
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.
LASER is Light amplification by stimulated emission of radiation. As far as I have understood, Solid State laser is a macroscopic form of diode laser. Thus a small semiconductor diode is similar to a solid state laser except for the mechanism of lasing and size.
To shoot a laser in Game Maker 8, you can create an object for the laser and use the "keyboard_check_pressed" function to detect when a key is pressed to shoot the laser. Then, use the "instance_create" function to create instances of the laser object at the desired position. You can set the speed and direction of the laser object in its create event.

construction and working of semiconductor laser
A diode is used primarily as a Rectifier
Yes, that is a laser diode
A laser diode module is useful when a small laser with lower power usage is needed. The diode is used in a multitude of fields, including life science, industrial, and scientific instrumentation.
Not usually. Laser pointers are usually diode lasers.
When one remove the focusing barrel of the laser diode.

One can purchase laser diode modules on select places around the Hong Kong. OPELUS is the best place to purchase laser diode Modules, Infrared Laser Module, Green Laser Module etc.
