Invention employs a unique combination of semiconductor optical amplifier and nonlinear optical filter to achieve wavelength conversion and regeneration.

Hybrid optical device

A diode pumped doubling system employs a pump diode, a crystal and doubler in a laser cavity with the diode and is operated in a pulsed or low duty cycle pumping regimen, while the cavity length is sufficiently short to stabilize the transient responses to pulsed diode operation and produce stable and known or controlled energy output under the non-CW pumping regimen. The construction allows stable output to be maintained with much looser temperature control, and to be achieved during the initial turn-on interval of the laser diode. In a preferred embodiment, the device employs a doubler which is clamped across its non-critical axis, and is operated with a control system which creates isotherms in the active mode volume. The controller operates one or more separate heat sources and/or sinks to preheat the diode source or doubling crystal to maintain an oriented thermal gradient, and the rate or direction at which the isotherm migrates across the mode volume is controlled in accordance with the forthcoming pulse sequence to maintain effectively stable conditions during laser operation. The thermal control system may include sink, heater and control elements for pre-heating the laser diode before actuation, and during quiet intervals.

Pulsed laser with passive stabilization

A fiber optic connector system. A first connector (25) associated with the fiber (15) includes a fiber holder (40) and a first engagement member. A second complementary connector (30) includes a fiber receptacle (95) and a second engagement member (90). The fiber holder is maintained in a precise position by the second connector when the first and second engagement members engage one another. The second connector may be associated with a radiation source. Associated with the first connector is a contact element (75) electrically coupled to the first engagement member through a network (80) for establishing a defined electrical characteristic therebetween. A second contact element (92, 103) associated with the second connector is normally insulated from the second engagement member and is mounted relative to the second engagement member so that the first and second contact elements make electrical contact with each other when the first and second engagement members are mechanically engaged with each other. Sensing circuitry (32) provides an electrical signal that represents the electrical characteristic between the second contact element and the second engagement member. Thus, when the first connector is engaged with the second connector, the signal represents the defined characteristic. Different type of fibers are provided with different values of this characteristic in the connector.
