This invention discloses an all-solid-state white laser, belonging to the field of laser technology. The laser includes a pump source for generating pump light and a composite laser gain medium for receiving the pump light. The composite laser gain medium is composed of several laser crystals with a stepped distribution of pump light absorption coefficients and several nonlinear optical crystals arranged in a cross-bonded configuration. A first laser resonator, a second laser resonator, and a third laser resonator are formed by coating the laser crystals and nonlinear optical crystals respectively, enabling them to generate lasers of different wavelengths in the same direction under the action of focused pump light. The first laser output from the first laser resonator, the second laser output from the second laser resonator, and the third laser output from the third laser resonator are mixed in the same direction to generate white light, which is then output. This invention effectively improves the thermal effect inside the gain medium through relatively independent resonators, which is beneficial for obtaining high-quality, high-power white light output.

This utility model relates to the field of power transmission equipment technology, specifically to a clamp device for spacers and a phase-to-phase spacer assembly. The device includes a clamp body and a pressure cap. One end of the clamp body is used to connect to the spacer; one end of the pressure cap is rotatably mounted on the clamp body, forming two clamping plates. A wire hole for holding the wire is provided between the pressure cap and the clamp body. A locking part is provided at the other end of the pressure cap. The clamp body has a sliding groove, within which a locking pin slides. When the locking pin slides to the end of the groove near the pressure cap, it abuts against the locking part when the pressure cap is closed, thus restricting the pressure cap from rotating open. When the locking pin slides to the other end of the groove, it disengages from the locking part. The clamp body has an elastic element, with its two ends abutting against the locking pin and the clamp body respectively. Applying external force to push the locking pin and compress the elastic element allows the pressure cap to be opened and the power transmission wire inserted. After closing the pressure cap, removing the external force pushes the elastic element to push the locking pin against the locking part, preventing the pressure cap from loosening. This design is convenient to use.
