Abstract: System and method for utilizing a serial array (10) of large laser cores (11), positioned inside an external cavity formed with full reflection mirrors (12) and a partial reflection mirror (13), containing a mode-selection mechanism, based on a seeding laser (14), a Fabry-Perot (16), and an isolator (15), for ensuring only the axial wave (17) can exist, generating correspondingly an output beam (18) of high power as well high beam quality.

Abstract: This invention opens up the chip thickness for increasing VCSEL power. It describes a method by using multiple gain layers 10, separated by insulating layers 11, powered in parallel electrically through embedded electrodes 13, 14 connected through via holes. The gain layers, as a whole, are bounded on top and bottom by DBR mirrors 12. The structure, compared to a standard VCSEL, leads to higher power, lower resistive loss, higher device speed, higher beam quality, and fewer number of DBR layers.

Abstract: System and method for operating a single unit of light-amplifying medium, structured to produce light with a complex spatial spectrum including multitude of high-order spatial modes, in external cavity configured, in conjunction with an optical etalon installed intra-cavity, to reduce spatial spectrum of such light to provide an output containing smaller number of high-order spatial modes and, optionally, only the lowest spatial mode at power levels on the order of 1 W or higher (for example, tens or hundreds of Watts).
