The reduced light behind the goggles may also cause the pupils to dilate, increasing the hazard to the invisible IR light. Maiman’s functional laser used a solid-state flashlamp-pumped synthetic ruby crystal to produce red laser light, at 694 nanometers wavelength; however, the device only was capable of pulsed operation, because of its three-level pumping design scheme.

Обладая несомненными достоинствами, особенно при демонстрации видео, CRT-проекторы имеют и ряд существенных недостатков, ограничивающих сферу их применения. The beam in the cavity and the output beam of the laser, when traveling in free space (or a homogeneous medium) rather than waveguides (as in an optical fiber laser), can be approximated as a Gaussian beam in most lasers; such beams exhibit the minimum divergence for a given diameter. Здесь наблюдается система светлых пятен, разделённых тёмными узловыми линиями. Springer. ISBN 0-306-45748-2. Taylor, Nick (2000).

Very occasionally laser gloves, which are sometimes mistaken for pointers, are seen being worn by professional dancers on stage at shows. Depending on the design of the cavity (whether the mirrors are flat or curved), the light coming out of the laser may spread out or form a narrow beam. In analogy to electronic oscillators, this device is sometimes called a laser oscillator.

Mass production of laser diodes for commercial devices like laser projectors have driven down prices.
