Abstract
A controlled spectrum generation laser arrangement achieving greater uniformity in the optical power spectral distribution is realized by employing a matching plate that conforms the boundary interface of the active medium with the shape of the focal surface of the pump radiation. The matching plate ensures that for any portion of the active medium the pump radiation is focused at its boundary interface so as to achieve a uniform pump beam intensity.
