Abstract

Research on amplification of ultrashort laser pulses at 1.03 µm in gain-managed nonlinearity regime

Highlights

Ultrafast laser sources with and high pulse energy are a topic of interest both in science and industry, especially when their wavelength are not reachable in traditional way
Pulses from the seed were directed into the amplifier, which consisted of 9-meter-long double-clad Ytterbium-doped polarization maintaining (PM) fiber with a 10-μm core diameter
It was pumped by a laser diode working at 918 nm

Summary

Introduction

Ultrafast laser sources with and high pulse energy are a topic of interest both in science and industry, especially when their wavelength are not reachable in traditional way. As a seed laser we used fiber laser with a repetition rate of 30.44 MHz, working at the central wavelength of 1031 nm and 11 nm of width (Fig. 1(b)). The compressed pulse duration was 312 fs at average power of 68.3 mW.
