A burst of X-rays, for example, might shatter the mirrors of conventional antimissile lasers.

In both cases, the energy was supplied by powerful conventional lasers.

A random laser uses no optical cavity but the remaining principles of operation remain the same as for a conventional laser.

The previous record was 24 gigahertz, established by scientists using a conventional laser.

In contrast, most "conventional" lasers (such as the ruby laser) rely on stimulated electronic transitions to amplify light.

However, this pumping does not produce a population inversion as in conventional lasers.

This is in contrast to conventional lasers, in which the possible laser output wavelengths are determined by the emission lines of the gain material.

In contrast, the wavelengths of most conventional lasers are fixed.

Fiber lasers are replacing conventional lasers in many applications.

The van der Waals interaction of atoms with surfaces makes it difficult to make the atomic mirrors, typical for conventional lasers.
