Laser with controlled geometry fluorescent converter
This patent describes a solid state laser having a laser gain medium and a light source with output light for optically pumping the medium, the medium having a predetermined pump light absorption band, the improvement of means for transmitting the medium output light within the absorption band and for converting at least part of the output light having a wavelength outside the band into light having a wavelength within the bank and transmitting to the same medium, comprising: a solid state fluorescent converter between the source and the medium being capable of transmitting part of the output light within the band and of producing flourescent radiation within the band in response to excitation by the out-of-band output light, the converter having a first plant side facing the source and a second side facing the medium, the second side comprising a plurality of surfaces extending in directions transversely of the plane of the first side and at angles thereto having magnitudes selected to transmit a substantial part of the flourescent radiation toward the medium.
