LD pumping
Compared with flashlamp pumping:
•     Higher efficiency
•     Higher average pump power
•     Higher reliability and life time
•     Lower heat deposition

Stored efficiency
•     pump wavelength 808 nm: ≈ 17%
•     pump wavelength 885 nm: ≈ 15%
•    LD pumping efficiency ~5 times higher than that of flashlamp
