Ask AI: What are the absorption coefficient and reduced scattering coefficient of water at 1064 nm laser beam?

The absorption coefficient (μa) and reduced scattering coefficient (μs') characterizes the attenuation of light as it passes through a medium such as water. These values are wavelength-dependent and can vary with water purity, temperature, and pressure. At a wavelength of 1064 nm, the typical values for water are as follows: 1. Absorption coefficient (μa): The absorption coefficient of water at 1064 nm is quite low, typically in the range of 0.01 cm⁻¹ to 0.1 cm⁻¹. 2. Reduced scattering coefficient (μs'): The reduced scattering coefficient at 1064 nm is difficult to accurately quantify due to its weak scattering property at longer wavelengths. However, the scattering generally decreases with increasing wavelength, resulting in a very low μs' (< 0.01 cm⁻¹) for water at 1064 nm. Please note that these values are approximate and may vary under different environmental conditions, water quality and purity. For precise measurements, it is recommended to perform experiments under controlled conditions or refer to specific scientific literature.

The absorption coefficient of water at 1064 nm is 0.031 cm-1, while the reduced scattering coefficient of water at 1064 nm is 0.9 cm-1.
