Multi-kilojoule petawatt lasers using chirped-pulse amplification need large-scale compression gratings. Tiled-grating approach has been adopted in several systems to meet the size requirements, grating tiles need to be precisely phased to ensure a transf
Photoassociation via reverse ladder transition controlled by two and four laser pulses is investigated using the time-dependent quantum wave packet method. The calculated results show that the amplitudes of the pulses have an enormous effect on the target
We demonstrated a diode-pumped Nd:YAG laser with a plano-concave resonator. When the pump power is 1.57 W, the output power of 1123-nm laser is 132 mW at the temperature of 20 oC, and the power change is less than 2% in an hour. A periodicallypoled LiNbO3
