Abstract: Solid optical materials such as glass which are to be used in laser systems may fail catastrophically due to the presence of microinhomogeneities. These microinhomogeneities are locatable by exposing the material to a laser pulse which preferably has a pulse duration of approximately 0.1 to 10 microseconds.

Abstract: A LASER ROD, HAVING A LENGTH TO LATERAL DIMENSION RATIO OF A LEAST ABOUT 1 TO 1 OR GREATER, IS FORMED OF AN UNANNEALED GLASS HAVING AN ACTIVE LASER INGREDIENT, AND THE ROD, MADE TO DESIRED DIMENSIONS, DURING ITS MANUFACTURE IS COOLED IN SUCH A MANNER THAT THERE IS A GRADIENT OF STRAIN FROM THE SURFACE TO THE CENTER AND BETWEEN THE END, PRODUCING A ZERO LENS EFFECT AT HIGH REPETITION RATES WHERE THE RESONANT OPTICALL ENERGY PRODUCES HIGH TEMPERATURES IN THE ROD. THE ROD IS PRODUCED WITH A NEGATIVE LENS EFFECT, AT LEAST AT SECTIONS INTERMEDIATE THE OPPOSED ENDS, WHICH IS SUBSTANTIALLY EQUAL TO THE POSITIVE LENS EFFECT PRODUCED BY EXPANSION OF THE ROD DUE TO THE HEATING DERIVED FROM OPTICAL PUMPING, TAKING INTO CONSIDERATION THE DIFFERENTIAL COLING EFFECT FROM THE EXTERIOR SURFACE INWARDLY OF THE ROD.

Abstract: The composite laser structure is self-aligning and; therefore, individual elements thereof are easily replaceable without contemporaneous adjustment. The method for fabricating and assembling the composite structure is also described.
