It is one of the most important questions to reduce the thermal effect and accumulation in the laser medium effectively, by pumping and lasing in the research of laser diode pump solid-state laser (DPSSL) at high power laser level. Compared with the conventional pumping scheme, direct pumping scheme at longer wavelength will not only reduce the heat by 30%～50%, but also improve the laser performances significantly. The development and status of direct pumping DPSSL based on the research of the Nd3+ doping laser are reviewed, the characteristics of the new pumping scheme and the progresses on Nd doping lasers are introduced. Finally, the new development in the future is prospected.
