You can find them in shops or online retailers and they may choose to record your identification details and ask you to explain what you want to use them for before deciding to sell you one. You will have difficulty finding laser pointers over 1 milliwatt (1 mW) in power.
There's more than one type of laser. Diode lasers are pretty much ready to go immediately, but you don't want them to push too much power, as they can then heat up to the point of failure. Other lasers, particularly high powered chemical lasers, rely on a several complicated sub-systems to fire, and will need quite some time to get ready for action.
High energy electrons are much easier to create than high energy photons.

Conventional lasers do not emit gamma radiation. Lasers use electromagnetic waves in the visible spectrum; this is light that you can actually see. Gamma rays are electromagnetic waves with much more energy and much higher frequency than visible light.

Type your answer here... i have no clue but they are high
Anywhere from $20 to $150. You get what you pay for.
The answer is pretty much "No." You can increase the power slightly, but if you go much beyond what it's designed for you'll burn out the laser diode.
In order to focus a high powered lens, you have to turn the knob using the scanning lens. Then rotate the high powered lens. But you must be careful as to not turn the knob so much that it cracks the slide because then you have to clean a glassy mess.

no, but it will make you bounce back
a Laser emits amplified light radiation energy, similar to the radiation from the sun. In fact, that's where the name comes from: Light Amplification by Stimulated Emission of Radiation.
