Light from an array of laser light sources are spread to cover the modulating face of a DMD or other modulator. The spread may be performed, for example, by a varying curvature array of lenslets, each laser light directed at one of the lenslets. Light from neighboring and/or nearby light sources overlap at a modulator. The lasers are energized at different energy/brightness levels causing the light illuminating the modulator to itself be modulated (locally dimmed). The modulator then further modulates the locally dimmed lights to produce a desired image. A projector according to the invention may utilize, for example, a single modulator sequentially illuminated or separate primary color modulators simultaneously illuminated.

There is provided a lens for a light emitter which includes: a bottom surface; an incident surface connected to the bottom surface at a central region of the bottom surface and disposed on or above a light source to allow light emitted from the light source to be made incident thereto and travel in an interior of the lens; and an output surface connected to the bottom surface at an edge of the bottom surface and configured to allow the light which has traveled in the interior of the lens to be emitted outwardly therefrom, wherein the central region of the bottom surface protrudes with respect to the other region of the bottom surface.

A system and method of generating white light for a projection system in a compact form factor using laser diodes, a reflection system, and a phosphor target. Light emitted from the laser diodes can be directed towards a region of the phosphor target, where the phosphor target is excited and emits light in a desired spectrum in all directions. Some emitted light is collected by a collection lens. The emitted light collected by the collection lens can be combined with light from the original laser diodes to create white light for use in the projection system. Light emitted in a direction away from the collection lens can be redirected to the collection lens by the reflection system that employs a curved reflector on one side of the phosphor target and a flat reflector on the opposite side of the phosphor target.

Apparatus and method for the amplification of a laser beam by pumping a homogenous composite source beam through an amplification medium. A slab crystalline active medium is side-pumped via a pump module having a laser diode bar and an optical assembly. The optical assembly has a fast axis collimator and a lens in the fast axis and an array of slow axis collimators and the lens in the slow axis.

Embodiments of multiple laser diode bars and optical assemblies are described together with double side pumping arrangements.
