Incoherent laser

The report considers prospects of development, on the basis of fibre lasers, of an ‘incoherent laser’ producing noise-like pulses. The possibility is demonstrated of a radically new radiation source occupying, in terms of output properties, an intermediate place between incandescent bulb and laser. Combination in such a laser of high output beam directivity, brightness and incoherent character of the radiation is quite important in many applications where speckle patterns of the light field are an undesirable effect.
