If so how can we do that?
Or a star.jbriggs444 said:You can refract it with a lens or a prism.

But for some smaller applications that might be impractical.
yup, but a really awesome and cool scaleboneh3ad said:I mean, isn't that technically still a (gravitational) lens, though?
Of course, in the case of a gravitational lens, the light is technically traveling in a straight line and we merely regard it as bent because of our prejudice toward the expected behavior of a space-time free from intrinsic curvature.boneh3ad said:I mean, isn't that technically still a (gravitational) lens, though?
I suspect that's a bit too advanced for this OPjbriggs444 said:Of course, in the case of a gravitational lens, the light is technically traveling in a straight line and we merely regard it as bent because of our prejudice toward the expected behavior of a space-time free from intrinsic curvature.
Yeah. The reason I mentioned it is that it is a lens that does not require the light to pass through - and be degraded by - a medium.boneh3ad said:I mean, isn't that technically still a (gravitational) lens, though?
Perhaps, but it might be unfair to second-guess the OP. They gave no clues about the intended application, or level of knowledge.phinds said:I suspect that's a bit too advanced for this OP
Based on the original question, I stand by my statement.DaveC426913 said:Perhaps, but it might be unfair to second-guess the OP. They gave no clues about the intended application, or level of knowledge.
A gradual change between different refractive indices will make a laser beam follow a Curved Path, which could be a bit more striking than a sharp kink on the way through. For that to happen (visibly) in air, you would need a long path and some extreme differences in temperature for two layers. But a laser beam can carry a long way and be visible from the side (dust scattering etc) so it may be realisable. Perhaps a fuzzy boundary between two miscible liquids would work.CWatters said:Material with graded refractive index. See also mirage.
I am shocked, shocked to find that is going on in here.phinds said:Anybody notice how we are just talking to ourselves here? The OP has not been back in the 8 days since he posted the question.
Yes, a laser beam can be bent. However, the extent to which it can be bent depends on several factors such as the wavelength of the laser, the material it is passing through, and the angle of incidence.
A laser beam can be bent using various methods such as using lenses, mirrors, or prisms. By manipulating the path of the laser beam, it can be directed to travel in a curved or angled direction.
Yes, it is possible to bend a laser beam without losing intensity. This can be achieved by using specialized lenses or mirrors that are designed to maintain the intensity of the laser beam while changing its direction.
Yes, a laser beam can be bent at a 90-degree angle. This can be achieved by using a combination of mirrors and lenses to reflect the laser beam at a right angle.
Yes, the direction of a laser beam can be controlled and adjusted using various techniques such as using mirrors, lenses, or prisms. This allows scientists to precisely direct and manipulate laser beams for various applications.
