Abstract :
We demonstrated the compensation of thermal lens effect regardless of pumping condition by inserting a solid-state CE, compensating element, having negative dn/dT property between two rods. This scheme of thermal compensation of rod systems is an ultimate method because of its dynamic compensation feature independent of the pumping power level.
