Summary:Summary form only given.It is now well established that ytterbium's simple spectroscopy and the low host crystal thermal loading that results from the ion's minimal quantum defect allow dramatic power scaling. Exactly how much heat is deposited into the host crystal at a given moment is intimately intertwined with the ion's excitation and de-excitation pathways. An optical resonator's stability strongly depends on the optical consequences of heat deposition, namely thermal lens and depolarization. It can therefore dramatically depend on the laser dynamics. We show that a side-pumped Yb:YAG rod is much less sensitive to these effects than an end-pumped one.
