摘要： A radial polarization disk laser, including a pumping source, a collimator lens, a focusing lens, a laser gain medium, a Brewster axial cone, and a output lens, which are sequentially arranged along a laser light path. An angle formed between the conical surface and the bottom surface of said Brewster axial cone is a Brewster's angle. Said laser gain medium is bonded with said bottom surface; said laser gain medium and said output lens form a laser harmonic oscillator cavity therebetween. The pumped laser light emitted by said pumping source passes through said collimator lens and said focusing lens, then is focused on the laser gain medium, and. the generated photons oscillate in said laser harmonic oscillator cavity, and then a radial polarized laser beam is finally output by said output lens.

摘要： An optical lens includes a first lens (L1), a second lens (L2), a third lens (L3), and a fourth lens (L4), which are successively coaxially arranged along the transmission direction of incident light, wherein the first lens (L1) and the fourth lens (L4) are negative meniscus lenses, the second lens (L2) is a positive meniscus lens, and the third lens (L3) is a positive plano-convex lens. The optical lens can be applied to an optical system of a laser processing device, when a utilized processing wavelength is different from a monitoring wavelength, the imaging chromatic aberration in a monitoring system may be eliminated, particularly when a wavelength of the far infrared region is utilized as a wavelength for laser processing. When using the red light wavelength as the monitoring wavelength, the monitoring system can achieve a better imaging effect, thus ensuring the quality of laser processing.

摘要： A submersible linear motor oil pumping system includes a submersible linear motor (100), an oil pump (200), a sealing device (300), and a balance assembly (400) installed underground. The submersible linear motor (100) includes a stator (10) and a mover (20) moving reciprocally inside the stator (10). The oil pump (200) includes a barrel (32), a piston (34), an outer sleeve (36), and a oil feeding sieve tube (38). The sealing device (300) is positioned between the submersible linear motor (100) and the oil pump (200). The balance assembly (400) is positioned at a lower end of the submersible linear motor (100) and is configured to balance pressure inside and outside the submersible linear motor (100). The present system omits the sucker rod of existing oil pumping systems, avoiding stroke loss caused by sucker rod elongation and energy loss caused by the weight of the sucker rod and pipe rod offset grinding, thereby improving the efficiency of the system.
