In the assembly of optical resonators of optically pumped semiconductor lasers (OPSL), the highly reflective resonator mirror is the most crucial component. In previous cooperation, Coherent and Fraunhofer IPT have developed a robust active alignment

For high precision beam steering usually complex and sophisticated mechanics are necessary to keep the alignment long term stable. Here we present a simple temperature controlled steering device based on a crystal with different temperature expansion

We achieved 100mW cw of 593nm by intracavity sum frequency generation in a branched cavity, dual laser set up. Two gain media were used: Nd:YVO4 for generating 1342nm, diode-pumped by 3.7W at 808nm, and an optically pumped semiconductor chip (OPS), d

We report on critically phase-matched second-harmonic generation of a diode-pumped Q-switched Nd:YLF laser with KNbO3. We discuss the temperature and intensity dependence of conversion efficiency and long-term degradation effects for more than 3 × 1

We report on efficient lasing of Pr-doped fluoride materials with cw output powers up to 600 mW in the visible spectral range. Praseodymium doped LiYF(4) and LiLuF(4) crystals were pumped either by an intracavity frequency doubled optically pumped se
