1 Introduction

With the rapid development of laser diode (LD) recently Yb 3+ doped laser materials as the gain medium in high-energy solid-state laser systems have obtained much attention [1 – 3] There are only two manifolds in the Yb 3+ energy level scheme namely the F 7 / 2 2 ground state and the F 5 / 2 2 excited state and the absorption band is located at about 970 nm with a large cross-section

Observation of squeezed light in the 2 $mat{μm}$

We present the generation and detection of squeezed light in the 2 $mat{mu m}$ wavelength region This experiment is a crucial step in realising the quantum noise reduction techniques that will be required for future generations of gravitational-wave detectors Squeezed vacuum is generated via degenerate optical parametric oscillation from a periodically-poled potassium titanyl phosphate

SUPPLEMENTARY INFORMATION

For the effective refractive index change due to harmonically driven mechanical deformation we have δβ(z t)= δn effk o sin(ω mt+ϕ)Π(z/L) (2) where δn eff is the change of effective refractive index k o is the vacuum wavevector ω m is the driving angular frequency

This material exhibits a unique cocktail of properties of use such as near unitary refractive index an order of magnitude lower thermal conductivity and high optothermal nonlinearity The latter two of these properties allow for the creation of localised steep thermal gradients proportionally affecting the low refractive index significantly
