Basically Si and Ge are optically inactive materials because of it's indiect band gap.That's why people are not using this for producing lasers.
Generally we are using Optically active materials are used for Laser Production.
Ex:Ga-As

What gem is commonly used when creating lasers?
Diamonds are commonly used when creating lasers.
What are green lasers used for?
Green lasers are used for lights of a particular place. Green lasers can also be used for airplanes and others. It also can make people to see.
What is the difference between cold and hot lasers?
Cold lasers are safer and deal less pain than hot lasers. Cold lasers are usually used for repairing skin damage and treating pain and inflammation. Hot lasers are simply used for burning things.
Are there any lasers that can cut through metal?
Absolutely. There are many lasers used in industry for metal cutting. CO2 lasers are the most common, but there are many other types.
What are the potential harmful effects of lasers?
Lasers produce a strong beam of light. If you understand that light is energy then you will understand that a laser delivers energy to a point where the beam strikes. That energy can be weak - most domestic lasers are very low energy - and is only dangerous if focused on your retina. Like looking at the sun, looking directly at a laser can burn little permanent scars on your retina. Running it over your fingers does nothing. Commercial lasers are another story. Powerful lasers are widely used for cutting steel plates in the same way an oxy-acetylene torch does. Those lasers would cut your hand off as quickly as a butchers saw. And military lasers are big-brothers of the commercial ones. They are designed to cut holes in orbiting satellites at ranges of thousands of miles. Powerful indeed.

What are quantum dots used for?
Quantum dots are semiconductors that are used for medical imaging, quantum computing, transistors, solar cells, LEDs, and diode lasers. It was discovered by Alexei Ekimov in the early 1980s.
Do nuclear reactors use lasers?
No, but experiments with lasers to produce nuclear fusionare being conducted, and this technique may be used sometime in the future in a fusion nuclear reactor.
What type of lasers does Intralase produce?
Intralase produces Lasers that can be used for eye surgery. The eye surgery that can be performed is called LASIK and this stands for Laser-Assisted In Situ Keratomileusis.
What is used in semiconductors?
Silicon based semiconductors are the most commonly used semiconductor material in calculators. Silicon semiconductors are also extensively used in computers.
Why are metalloids semiconductors?
Metalloids when used is electronics are called semiconductors.
Are gems used in lasers?
are gems used as rubies called lasers
Are rubies used in electronics?
Yes, rubies are used in some LASERs. These LASERs are (not surprisingly) called ruby LASERs.
What are TopCon lasers used for?
The TopCon lasers are used in the construction industry These lasers are used as positioning equipment and are used by surveyors, civil engineers, construction contractors and equipment operators.
What gem is commonly used when creating lasers?
Diamonds are commonly used when creating lasers.
Is scandium used for lasers?
I suppose that scandium was used up today in garnet lasers.
What are green lasers used for?
Green lasers are used for lights of a particular place. Green lasers can also be used for airplanes and others. It also can make people to see.
