<p>The tunable dye stuff laser resonator consists of at least one mirror and a reflection refracting grid. The grid troughs are of such flank steepness and depth in the direction at right angles to the division that these two parameters are continuously decreased from the beginning of the division to its end. The rotary axis of the grid is outside the intersection point of the resonator axis with the grid surface. Preferably the rotary axis of the grid is at one centre vertical of the grid, and at right angles to the same at the mean tuning wavelength of the laser. The effectiveness of grid for the polarisation direction is at its optimum orthogonally to the grid troughs.</p> |
