Latest developments on membrane external-cavity surface-emitting lasers (MECSELs) — •Hermann Kahle1,2, Patrik Rajala2, Philipp Tatar-Mathes2, and Mircea Guina2 — 1Institute for Photonic Quantum Systems (PhoQS), Department of Physics, Paderborn University, Warburger Straße 100, 33098 Paderborn, Germany — 2Optoelectronics Research Centre (ORC), Physics Unit / Photonics, Tampere University, Korkeakoulunkatu 3, 33720 Tampere, Finland
MECSELs have experienced a rapid progress in recent years. Based on the membrane geometry of MECSELs, an intrinsically excellent beam quality is one important benefit of this new vertically emitting kind of lasers. The most important recent progress, like continuous wave broadband tuning (ΔλFWHM ≈ 70 nm around λ0 = 985 nm) and anti-resonant gain membrane design will be discussed.
