    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 radially polarized thin disk laser comprises a pumping source (10), a collimating lens (20), a focusing lens (30), a laser gain medium (50), a heat dissipating medium (55), a Brewster biaxial cone (60), and an output lens (70) which are arranged in sequence along the laser light path. The Brewster biaxial cone (60) comprises two opposite cones and a cylinder connecting the two cones. The angles between the conical surfaces (S5,S7) and bottom surfaces of the cones are the Brewster angle. The laser gain medium (50) is bonded to the heat dissipating medium (55). A laser sub-resonator is formed between the laser gain medium (50) and the output lens (70). After passing through the collimating lens (20) and the focusing lens (30), the pumping laser beam emitted from the pumping source (10) is focused on the laser gain medium (50), then the generated photons resonate in the laser sub-resonator and finally a radially polarized laser beam is outputted from the output lens (70).
