Input Laser Light Signal

AI Thread Summary

Laser amplification can be achieved using an external light source, but it can also originate from spontaneous emission within the lasing material itself. The initial input light signal is crucial for the amplification process. Seeding a laser with another laser, as seen in tunable lasers like Ti:Sapphire, is a common practice. This method allows for enhanced control over the output characteristics of the laser. Understanding these mechanisms is essential for optimizing laser performance.

hi , does input light signal for laser amplification has to be provided by the external source or it is created by lasing material itself?

Every laser starts from the background signal given by spontaneous emission.

You can also seed one laser with a different laser as is typical for tunable lasers like Ti:Sapph.

Thread 'Max Photon Energy: Planck Length Lower Limit?'

Planck length is ~ 1.6\times 10^{-35} meters. Does this mean that this may be a lower limit on meaningful wavelength and therefore upper limit on energy?

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
