Abstract
A system, comprising: a first array of lasers; a first linear polarizer; a second array of lasers; a second linear polarizer provided at an angle with respect to the first linear polarizer; a first beamsplitter coupled to the first linear polarizer; a phosphor assembly; a collimator lens; a third linear polarizer; a second beamsplitter coupled to the third linear polarizer; and a telephoto lens.
Claims20
A system, comprising:
- a first array of lasers to emit a first light;
- a first linear polarizer to receive the first light;
- a second array of lasers to emit a second light;
- a second linear polarizer to receive the second light, the second linear polarizer provided at an angle with respect to the first linear polarizer;
- a phosphor assembly positioned in optical communication with the first array of lasers and the second array of lasers to receive the first light and the second light and generate a non-coherent light;
- and
- a collimator lens to collimate the non-coherent light to obtain collimated non-coherent light.

A system, comprising:
- a first array of lasers adapted to emit first light;
- a first linear polarizer adapted to polarize the first light, forming polarized first light;
- a second array of lasers adapted to emit second light;
- a second linear polarizer adapted to polarize the second light, forming polarized second light;
- a first beamsplitter, coupled to the first linear polarizer, adapted to:
- receive the polarized first light from the first linear polarizer and transmit at least a portion of the polarized first light as transmitted first light, and
- receive the polarized second light from the second linear polarizer and reflect at least a portion of the polarized second light as reflected second light;
- a phosphor assembly adapted to:
- receive a combination of light comprising the transmitted first light and the reflected second light, and
- generate, in response to receiving the combination of light, non-coherent light;
- a first lens adapted to receive the non-coherent light and collimate the non-coherent light to generate collimated non-coherent light;
- a second beamsplitter adapted to receive the collimated non-coherent light and reflect at least a portion of the collimated non-coherent light;
- and
- a second lens adapted to receive the at least a portion of the collimated non-coherent light reflected from the second beamsplitter and output focused collimated non-coherent light.
