| 英文摘要 | An optical resonator has an axial mode frequency tuning rate with respect to temperature matching the peak gain frequency tuning rate, so that mode hops are eliminated. The resonator contains a composite cavity consisting of a gain medium and free space. Preferably, the resonator is a single-frequency solid state laser containing a solid state gain medium defining a physical path length Lg. The optical cavity is defined by a high reflector and output coupler surrounding the gain medium and defining a physical cavity path length Lo. The high reflector and output coupler are mounted on a substrate so that Lo is temperature insensitive. Preferably, the substrate is a thermally insensitive material having a negligible coefficient of thermal expansion; for example, it may be Invar(TM), Super-Invar(TM), ULE(TM) Glass, Zerodur(TM), and fused silica. Alternately, the substrate is a thermally isolated material that is temperature controlled and insulated from the gain medium. When Lo=Lg, the axial mode tuning rate has a greater magnitude than the peak gain tuning rate. However, Lo/Lg is fixed and designed so that the axial mode tuning rate is identical to the peak gain tuning rate. In particular,The laser preferably contains means for ensuring single-frequency operation. For a ring laser, it may include a magnet and half-wave plate inside the cavity, coupled with rod-shaped gain material with anti-parallel Brewster facets. For a non-planar ring oscillator, the purpose of the half-wave plate is instead served by the non-planar path. Alternately, the resonator is an optical parametric oscillator. |
