    Abstract

    Radially polarized beam is one of the present hotspots and has great potential applications in many fields due to its special focus properties and polarization state. It becomes a hot technology to acquire radially polarized beam by use of photonic crystal grating as the mode selector. We summarize the recent research progress on radially polarized solid-state laser. Concerning the previous research on microchip radially polarized laser, in which the output power is limited due to the strong thermal effects of the lasing material at intensive pumping, a bonded crystal is chosen as the lasing material to weaken the temperature gradient in the lasing area and thereafter the thermal lens effect at the presence of intensive pumping. And the recent progress of lasers based on bonded crystal such as continuous wave radially polarized solid-state laser, passively Q-switched radially polarized laser and actively Q-switched radially polarized laser is summarized.
