# Microsphere solid state biolasers

## TL;DR

This paper demonstrates biocompatible microsphere solid-state biolasers made from biomaterials, with simple fabrication, low lasing threshold, and high Q factor, suitable for biological applications.

## Contribution

It introduces a novel, simple emulsion-based fabrication method for biolasers using biomaterials like bovine serum albumin, pectin, and cellulose.

## Key findings

- Lasing threshold of 1 microJ/mm2
- Q factor of 3000 measured
- Biocompatible with no interference in cell growth

## Abstract

Microsphere solid-state biolasers made of biomaterials-bovine serum albumin, pectin and cellulose are demonstrated. The fabrication is simple, based on emulsion, and with green processing. A lasing threshold of 1 microJ/mm2 and Q factor of 3000 are measured. The lasers are biocompatible, do not interfere with cell growth and division.
