Abstract： |
This invention relates to a pumping method for a 45deg. clino-axis and a pump module, which combines the advantages of parallel optical axis pump and vertical optical axis pump and puts forward a 45deg.clino-axis pump method and a pump module. Since the pump light is transmitted in zigzag in the crystal, it ensures the uniformity of the pump and full absorption of the crystal to pump lights, it's more suitable for solid laser materials with low absorption coefficient and fine output beams, besides, the total reflection of the 45deg. can reduce the interface reflection loss and cost of a laser crystal, the coupled face of 45deg. cutting increases the coupled face by 1.4times, move pump lights are coupled in. |
