A method for the formation of a thin optical crystal layer (e. g. , a thin LiNbO optical single crystal layer) overlying a low dielectric constant substrate (e. g. , a low dielectric constant glass substrate). The method includes implanting ions (e. g. , He ) through a surface of an optical crystal substrate. The implanting of the ions defines, in the optical crystal substrate, a thin ion-implanted optical crystal layer overlying a bulk optical crystal substrate. A low dielectric constant substrate is subsequently bonded to the surface, using either a direct or an indirect bonding technique, to form a bonded structure. The bonded structure is thermally annealed at a temperature in the range of 300Â C. to 600Â C. for 30 minutes to 300 minutes.

Solid-state laser(s) pumped by incoherent, monochromatic light from sources such as LED arrays and integrating technologies such as high power LED arrays and solid-state laser materials in conjunction with efficient and uniform absorption of pumping energies through a diffusing pump chamber. The resulting laser(s) are compact, robust, low-cost, and able to produce high power output for practical applications. It may efficiently operate over wide temperature and performance ranges, at CW or pulse modes, even with ultra short pulse width and/or extremely high repetition rates. Our inventive structure(s) is/are highly flexible and applicable to a large group of lasing media including those with very short upper state life times. Advantageously, they may be applied to a plethora of laser systems at wavelengths that have important applications and unavailable to other direct pumping technologies.
