The stimulated Raman process (SRP) is a critical technique in microscopy and spectroscopy, enabling applications such as real-time imaging of living cells and organisms [1,2]. Given the significance of SRP for photosensitive materials, there is considerable interest in enhancing its resolution without relying on high-intensity laser fields. To address this challenge, we leverage squeezed states of light, which exhibit reduced quantum fluctuations and improved signal-to-noise ratios, to investigate SRP. Our study highlights the benefits of utilizing squeezed light to enhance the precision of SRP measurements and compares its performance to that of classical light fields. [1] R.
