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.

Background

BACKGROUND (1) A laser is a device that emits light through a process of optical amplification. The process of optical amplification may be based on a stimulated emission of electromagnetic radiation. Unlike other sources of light, a laser produces a narrow beam of light by way of spatial coherence. The narrow beam may be utilized in different applications. SUMMARY (2) In some implementations, a system, comprising: a first array of lasers adapted to emit first light; a first linear polarizer adapted to receive the first light and provide the first light; a second array of lasers adapted to emit second light; a second linear polarizer adapted to receive the second light and provide the second light; a first beamsplitter adapted to: receive the first light from the first linear polarizer and transmit the first light as transmitted first light, and receive the second light from the second linear polarizer and reflect the second light as reflected second light; a third linear polarizer adapted to receive the transmitted first light and the reflected second light and provide the transmitted first light and the reflected second light; a phosphor assembly adapted to: receive the transmitted first light and the reflected second light, and generate non-coherent light based on a combination of the transmitted first light and the reflected second light; a collimator lens adapted to receive the non-coherent light and collimate the non-coherent light to generate collimated non-coherent li
