Abstract
A precise analysis of the biological remains is presented in the paper. A single-channel waveguide carbon dioxide laser is used in a process of ablation ‘ for the exposing of biological remains of mineralised organisms found in a sea slime used as a component in some technological process.Many important applications of the laser base on the process of ablation. These include also so precise biomedical uses like structural studies of biomolecules. Among of the wide range of the laser devices the waveguide carbon dioxide lasers can be used in a precise biological investigations. A single-channel waveguide CO2 laser emits very easy the optical wave formed in a single, so called quasi-Gaussian, mode2. The distribution of the intensity of the laser output radiation in a basic Gaussian mode is shown in Figure 1. A high quality laser output beam in a basic Gaussian mode can be easy focused permitting a precise ablation of the investigated material in a very small area of 100 μm and less.
