研究目的
Investigating the high power continuous-wave operation of a diode-pumped Yb:YAP laser.
研究成果
The diode-pumped Yb:YAP laser generated >7 W of output power at 22 W of pump power with a slope efficiency of around 70%. Owing to the high thermal conductivity and broad gain bandwidth, Yb:YAP is a suitable candidate for high power CW and pulsed regime of operation.
研究不足
The laser exhibited a noticeable thermal lensing effect in high power regime of operation.
1:Experimental Design and Method Selection:
A three-mirror laser cavity configuration was used with a 3 mm-long 5 at.% Yb:YAP (c-cut) crystal. The laser was pumped by a fiber-coupled laser diode with the maximum power of 22 W at 979 nm.
2:Sample Selection and Data Sources:
The pump power absorption in the crystal was measured at moderate and high power.
3:List of Experimental Equipment and Materials:
A fiber-coupled laser diode, Yb:YAP crystal, and three-mirror laser cavity.
4:Experimental Procedures and Operational Workflow:
The laser output power was measured versus absorbed pump power for different output couplings. The laser beam quality was measured at moderate output power.
5:Data Analysis Methods:
The slope efficiency was calculated, and the beam quality was analyzed using a modified beam propagation technique.
