Abstract
We report on a new monolithic high-power diode pumped Er:YAG solid state laser at 2.94 µm. The pulsed laser reaches 30Waverage output power and 150mJ pulse energy. To accomplish these high powers the thermal lensing of Er:YAG was modeled beyond ABCD matrix formalism with FEM simulations. With the well understood thermal lensing e ect alternative laser cavities have been designed for higher brightness. The predicted results t the theoretically simulated performance and with that an improved beam quality factor of M2 = 12 has been achieved with 100mJ pulse energy.
