Abstract
The present invention relates to a continuously tuneable free space laser. An amplifying medium in free space is placed inside a Fabry-Perot cavity consisting of two reflectors. One of these two mirrors being partially translucent and makes up the output mirror of the laser. According to the invention, the output mirror is inserted into the core of a monomode optic fiber that constitutes an output optic fiber and a lens placed in the Fabry-Perot cavity. This ensures coupling in this fiber of the luminous fluxes transmitted by the amplifying medium and the second reflector is self-aligned.
