Design of LD in-band direct-pumping side surface polished micro-rod Nd:YVO4 laser |
Pump intensity distributions normalized by the maximum in a 1-mm-diameter 50-mm-long micro-rod crystal [(a) and (c)] and traditional rod crystal [(b) and (d)]. The 888-nm pump beam radius is 200-μm and the far field divergence angle is 0.11. |
