摘要： A selective reflector (10), for selectively preventing reflection of light passing therethrough. The selective reflector (10) comprising at least one layer characterized by an angle-dependent reflectivity function. The angle-dependent reflectivity function being decreasing upon at least one interval of increasing impinging angle of the light on a surface of the at least one layer, such that when said impinging angle is within a predetermined range, the reflection of light is substantially prevented.

摘要： Apparatus (Figure 3, Character 10) for frequency conversion of light, the apparatus comprises: a light-emitting device (Figure 3, Character 201) for emitting a light having a first frequency, the light-emitting device (Figure 3, Character 201) being an edge-emitting semiconductor light-emitting diode having an extended waveguide (Figure 3, Character 204) selected such that a fundamental transverse mode of the extended waveguide (Figure 3, Character 204) is characterized by a low beam divergence. The apparatus (Figure 3, Character 10) further comprises a light-reflector (Figure 3, Character 214), constructed and designed so that the light passes a plurality of times through an external cavity (Figure 3, Character 212), defined between the light-emitting device and the light-reflector, and provides a feedback for generating a laser light having the first frequency. The apparatus (Figure 3, Character 10) further comprises a non-linear optical crystal (Figure 3, Character 213), positioned in the external cavity (Figure 3, Character 212) and selected so that when the laser light having the first frequency passes a plurality of times through the non-linear optical crystal (Figure 3, Character 213), the first frequency is converted to a second frequency being different from the first frequency.
