An array of vertical-cavity surface emitting lasers (VCSELs) may be fabricated with very high fill-factors, thereby enabling very high output power densities during pulse, quasi-continuous wave (QCW), and continuous wave (CW) operation. This high fill-factor is achieved using asymmetrical pillars in a rectangular packing scheme as opposed prior art pillar shapes and packing schemes. The use of asymmetrical pillars maintains high efficiency operation of VCSELs by maintaining minimal current injection distance from the metal contacts to the laser active region and by maintaining efficient waste heat extraction from the VCSEL. This packing scheme for very high fill-factor VCSEL arrays is directly applicable for next generation high-power, substrate removed, VCSEL arrays.

A single camera capable of capturing high speed laser return pulses for a target, as well as provide imaging information on the background of the target. This capability is enabled by having a read-out integrated circuit (ROIC) capable of extracting both types of information from a pixel of a focal plane array (FPA). Further, an ROIC topology that allows for the ability to distinguish between high frequency and low frequency signal paths, and provide supporting circuitry to process the two paths separately. One path may integrate the low frequency background scene to provide a high fidelity image of the scene. The second path may process high frequency noise and multiple laser pulse returns within a frame. These two paths may be combined to provide a background image with a superimposed laser return.

A wavelength selectable light source is comprised of a two-dimensional (2-D) array of variable wavelength vertical-cavity surface-emitting lasers (VCSELs), wherein light beams emitted from the VCSELs are coupled into an output optical fiber. The light beams emitted from the VCSELs are collimated via a 2-D array of micro-lenses, the collimated light beams impinge upon a first fixed-position mirror that points each of the collimated light beams toward a second movable mirror located at a common focal point in a common area, and the second movable mirror redirects the collimated light beams into a lens coupled to the output optical fiber. By moving the second movable mirror, different ones of the collimated light beams can be directed into the output optical fiber, so that the second movable mirror performs a wavelength selection function.

Embodiments of the invention describe an illuminator having a light source to originate an illumination beam, wherein the light source further comprises a set of vertical-cavity surface emitting lasers (VCSELs), including a first VCSEL having a first laser emission wavelength, and a second VCSEL having a second laser emission wavelength different than the first laser emission wavelength. Thus, by varying laser emission wavelengths of VCSELs in a VCSEL array, embodiments of the invention produce low-contrast speckle, and do not limit the imaging capabilities of the host illumination system. In some embodiments of the invention, vertical external cavity surface emitting lasers (VECSELs) are utilized to produce the above described varying laser emission wavelengths.
