Efficient generation of spatially-restructurable high-order hg-modes in a laser cavity

A laser system, comprising:

• a linear laser cavity having a laser cavity axis and defined by first and second reflectors;
• a laser gain medium chip containing said first reflector;
• the second reflector dimensioned to have a center of curvature of the second reflector at an axial point of the first reflector, and
• multiple pump channels configured to deliver pumping energy to the laser gain medium chip at respectively-corresponding multiple initial locations of a surface of the laser gain medium chip in a fashion that allows for spatially-varying said multiple initial locations wherein a number of said multiple initial locations is even,
• wherein said multiple initial locations form pairs of initial locations, initial locations in a first pair are defined on a first axis, initial locations in a second pair are defined on a second axis, the first and second axes being transverse to one another.
