Power Scaling of Narrow-Linewidth Mid-IR Spherical Microlasers

TL;DR

This paper explores power scaling in mid-infrared Er:ZBLAN spherical microlasers, demonstrating near-milliwatt output from a narrow-linewidth laser at 2.71 micrometers, advancing mid-IR laser technology.

Contribution

It presents the first demonstration of near-milliwatt power levels in narrow-linewidth mid-IR Er:ZBLAN spherical microlasers.

Findings

Achieved near-milliwatt power output

Narrow linewidth (< 50 pm) at 2.71 μm

Insights into power scaling challenges

Abstract

We discuss issues re: power scaling of mid-IR Er:ZBLAN spherical microlasers and demonstrate achievement of near-milliwatt power levels from a narrow-linewidth (< 50 pm) 2.71 um laser source based on an Er:ZBLAN microlaser.
