You haven't defined what you mean by "damaged" or "easily". According to
the typical popular understanding, probably the retina of the eye.
Retina of your eye is most susceptible to the damage by laser rays.
Any rocks can be "damaged" by freezing
The intensity of light from most light sources is inversely proportional to the square of the distance from the source. So the intensity two meters from an incandescent lamp is one quarter of the intensity at one meter, and at three meters from the lamp the intensity is one ninth of the intensity at one meter. Laser light ideally has the same intensity at any distance.
Laser is non diverging one and monochromatic. It is coherent and hence highly intense. So laser could be sent even to reach moon's surface and get it back reflected. So distance of astronomical objects could be found.

yes, like most metals...
The eyes are the most vulnerable part of the body to be damaged by a laser beam. The intense concentration of light can cause serious harm to the delicate tissues of the eyes, leading to vision loss or even permanent blindness. It is crucial to use appropriate eye protection when working with lasers or being exposed to laser beams.
The most common method is through the use of a beam splitter. This employs -- to keep it simple -- a partially transparent mirror placed at a 45 degree angle relative to the laser beam. Some of the beam passes through the mirror, and the rest is reflected perpendicular to the original beam by the mirror.
To get a LASER to work you need to excite it with energy. The most workable form of energy to do that is electricity. There ae several ways of exciting LASERs to work.
Orgasms or "climaxes" are the build up and "explosion" of pleasure. When a spot of pleasure is hit repeatedly (sometimes fast and hard), a build up of pleasure begins. When your body hits the point where it can't take the pleasure anymore, it releases it's build up, hence the orgasm part.
Well... Most LEDs, Light Emitting Diodes, have a very narrow wavelength span, so they'd fit part of your question. However, they're not always that intense. So you're probably asking about a LASER.
Laser skin resurfacing involves an intense light beam which can cause burning sensations. Most doctors will give an anesthetic to ease the discomfort.
Two most important :- 1. The beam should be perfectly coherent and, 2. Amplification and Stimulation should be at high level
Yes, but like light, the width of the beam will have to be several wavelengths or diffraction will mean most of the energy will just leak out sideways.
laser cutter? laser cutter can be thought of as three main parts: a laser, a controller, and a surface. The laser is like a pencil - the beam emitted from it allows the controller to trace patterns onto the surface. The controller (usually a computer) controls the direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface is picked to match what the laser can act on.laser engraving machineThere are three main genres of : The most common is the X-Y table where, usually, the workpiece (surface) is stationary and the laser optics move around in X and Y directions, directing the laser beam to draw vectors. Sometimes the laser is stationary and the workpiece moves. Sometimes the workpiece moves in the Y axis and the laser in the X axis. A second genre is for cylindrical workpieces (or flat workpieces mounted around a cylinder) where the laser effectively traverses a fine helix and on/off laser pulsing produces the desired image on a raster basis. In the third method, both the laser and workpiece are stationary and galvo mirrors move the laser beam over the workpiece surface. Laser engraving machine using this technology can work in either raster or vector mode.
The most important part of an optical disc drive is an optical path, placed in a pickup head (PUH),[1] usually consisting of semiconductor laser, a lens for guiding the laser beam, and photo-diodes detecting the light reflection from disc's surface.
As the question asked about "passing through" a laser sensor, the answer speaks to the breaking of the laser beam. And that's not something that you can do. Breaking the beam will trigger the sensor. If an investigator has an idea about the laser itself, it may be possible to "substitute" for the beam being used in the sensor, but most laser sensors will pick up any attempts to dump another beam in over the top of the extant one. Forget about mirrors and such. The "smart" laser sensors use a beam too small to "split" with mirrors. Rerouting with fiber optics is equally futile. What you've seen on those TV shows and in movies is pie in the sky - you can't do that. About all you can do is detect the beam and avoid it.It might be worth noting that anyone using a laser may also be using infrared IR sensors. (I would.) These sensors are notlasers and are completely passive; they emit nothing at alland cannot be "seen" in any way. (See the link below "What is a PIR alarm system?" for more details). If something is worth protecting with a laser, an IR detector would be an easy "add on" to that system. In fact, given a choice, the IR would be a better first choice.
Most lasers can be seen, and yes a green laser beam can be seen in space. But some lasers are really strong so we can't see them.
