## Summary

In their paper titled "Squeezed Lasing," authors Carlos Sánchez Muñoz and Dieter Jaksch introduce the innovative concept of a squeezed laser. This unique design involves a squeezed cavity mode that develops significant photonic occupation through stimulated emission, resulting in both spectral purity and photon correlations specific to a photonic mode with squeezed quadratures. The proposed implementation of this technology relies on parametric driving of the cavity and dissipative stabilization using a broadband squeezed vacuum, opening up new possibilities for applications beyond those achievable with standard lasers. One notable application highlighted in the study is the potential use of the squeezed laser in Michelson interferometry, enabling measurements beyond the standard quantum limit. Additionally, it shows promise for enhancing precision in atomic metrology applications. In their updated version, the authors delve into additional aspects such as intra-cavity losses, symmetry-broken solutions, spectrum of squeezing, and operation within a Michelson interferometer setup. This comprehensive investigation further underscores the versatility and potential impact of squeezed lasing technology in various scientific and technological fields.
