Abstract
There is provided an apparatus for wavelength conversion, comprising a wavelength converter, a first reflector, a second reflector, a third reflector, and a first lens. The first reflector has a curvature and is configured to reflect a plurality of input light beams onto the second reflector. The second reflector is configured to reflect the input light onto the third reflector. The first lens is disposed between the wavelength converter and the third reflector. The third reflector is configured to reflect the input light through the first lens and onto the wavelength converter, which is then excited to emit an emitted light. The first lens is configured to receive at least a portion of the emitted light, reduce its divergence, and at least partially transmit it to form an output light propagating towards the third reflector, which is configured to at least partially transmit the output light.
