    Abstract: A speckle laser device based on low time coherence and low spatial coherence, and a preparation method therefor. The speckle laser device comprises a radio frequency modulator (1), a laser device (2), a diffracting optical element (3) and a focusing lens (4) that are coaxially and sequentially disposed on a same optical platform. The diffracting optical element (3) is located in the emergent direction of the laser device (2), the radio frequency modulator (1) modulates the laser device (2), and laser (001) modulated by the radio frequency modulator (1) enters the diffracting optical element (3). Laser beams emerging from the diffracting optical element (3) are zero-coherent speckle laser beams (002), the laser beams (002) enter the focusing lens (4), and the laser emerging from the focusing lens (4) forms a focused speckle laser (003). Speckle laser output beams are obtained by using a time coherence and spatial coherence reduction technology, and the problem of speckle production due to time coherence and spatial coherence is resolved.

    Abstract: This invention proposes to use a specially designed layered nonlinear optic (LNO) for intracavity harmonic generation. The LNO generates the harmonic and guides the generated harmonic beam to a different path from the fundamental beam path with total internal reflection, a phenomenon that all lights are reflected when lights in one (“internal”) optic strike sufficiently obliquely against the interface with a second (“external”) optic, in which the refractive index is lower than that in the internal optic. No coating is necessary for the harmonic inside the fundamental beam laser cavity. The generated harmonic beam does not travel through any surface inside the fundamental beam cavity, either. Hence this invention improves the reliability of intracavity harmonic generation laser especially if the harmonic is in the UV range.
