Solid crystal laser-emission device with an external cooling circuit.

摘要

The device comprises a circuit for cooling the crystal and the discharge tube outside the pumping cavity (20). Inside the pumping cavity provided with a reflector (3) of elliptical cross-section, the device comprises an emission crystal (1) and a discharge tube (2) with axes of symmetry cooinciding with a focal line of the reflector respectively. The circuit for cooling the crystal (1) comprises at least one thermal conductor (21) in contact with the crystal (1). The circuit for cooling the discharge tube comprises at least one thermal conductor (23) in contact with the discharge tube. Each thermal conductor (21), (23) is also in contact with a dissipative wall (22) of the pumping cavity (20). The discharge tube (2) comprises a parallel firing electrode consisting of a rectilinear wire (27) insulated from the reflector (3) by an insulating tube (271).
