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.
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.
yes
yes, just look it up on youtube, there will be instructional videos! good luck!
Electron-hole recombination
i think in order to population inversion in depletion region. also the laser diodes must be degenerated.
you dont!

Hope not!
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.
construction and working of semiconductor laser
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.
