Abstract:
A laser pump cavity apparatus with integral concentrator, comprising:a doped solid-state lasing medium providing an active lasing region having a top surface, a bottom surface and at least two edge surfaces, surrounding a laser beam axis; anda concentrator comprising:a top cladding layer formed on the top surface of the active lasing region and having a first concave cylindrical outer focusing surface, anda bottom cladding layer formed on the bottom surface of the active lasing region and having a second concave cylindrical outer focusing surface,whereinsaid first concave cylindrical outer focusing surface defines a first optical line focus located parallel to the laser beam axis and above said first surface, andsaid second concave cylindrical outer focusing surface defines a second optical line focus located parallel to the laser beam axis and below said second surface.
