Tunable microfluidic dye laser [PDF]
TRANSDUCERS '03. 12th International Conference on Solid-State Sensors, Actuators and Microsystems. Digest of Technical Papers (Cat. No.03TH8664), 2004 We present a tunable microfluidic dye laser fabricated in SU-8. The tunability is enabled by integrating a microfluidic diffusion mixer with an existing microfluidic dye laser design by Helbo et al. By controlling the relative flows in the mixer between a dye solution and a solvent, the concentration of dye in the laser cavity can be adjusted, allowing

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Tunable Brillouin and Raman microlasers using hybrid microbottle resonators
Nanophotonics, 2019 We realized a tunable Brillouin laser and a tunable Raman laser by using ultrahigh-quality-factor (Q) hybrid microbottle resonators. The whispering-gallery-mode microresonator-based Brillouin and Raman lasers possess unique advantages (e.g. low threshold,
