A thermal bistability-based method for real-time optimization of ultra-low threshold whispering gallery mode microlasers
نویسندگان
چکیده
A method based on thermal bistability for ultra-low threshold microlaser optimization is demonstrated. When sweeping the pump laser frequency across a pump resonance, the dynamic thermal bistability slows down the power variation. The resulting lineshape modification enables a real-time monitoring of the laser characteristic. We demonstrate this method for a functionalized microsphere exhibiting a sub-microwatt laser threshold. This approach is confirmed by comparing the results with a step-by-step recording in quasi-static thermal conditions. c © 2015 Optical Society of America

متن کاملLow-threshold whispering-gallery-mode microlasers fabricated in a Nd:glass substrate by three-dimensional femtosecond laser micromachining.
We report on fabrication of whispering-gallery-mode microlasers in a Nd:glass chip by femtosecond laser three-dimensional micromachining. The main fabrication procedures include the fabrication of freestanding microdisks supported by thin pillars by femtosecond laser ablation of the glass substrate immersed in water, followed by CO2 laser annealing for surface smoothing. The quality (Q) factor ...
متن کاملWGM Microrod Laser Fabricated by pulsed CO2 Laser Micromilling
Introduction Whispering Gallery Mode (WGM) microlasers have been of a great interest owing to their low threshold and narrow linewidth lasing due to their high Q and small mode volume. Most of the fabrication methods [1-3] are non-controllable and non-reproducible which rely on fiber-tip melting, such as microspheres [3, 4] or splicing of small active-fiber stubs [3]. Microresonators are realiz...
