Abstract

We present comparative studies of the laser performance of a diode-end-pumped, composite Tm:YAG rod with undoped ends. Efficient heat removal in a composite rod can reduce the peak of the rise in temperature in the 2-mm-long active segment by 19% compared with that in a noncomposite rod by theoretical calculation. The threshold pump power was reduced by 10%, and the focal power of the thermal lens was improved by 15%. These improvements permit high output performance and flexible design of laser cavities in diode-end-pumped Tm:YAG lasers.
