Passively Mode-Locked Raman Laser [PDF]
Physical Review Letters, 2010 We report on the observation of a novel mode locked optical comb generated at the Raman offset (Raman comb) in an optically pumped crystalline whispering gallery mode resonator. Mode locking is confirmed via measurement of the radio-frequency beat note produced by the optical comb on a fast photodiode.

Photoniques, 2023 Mode-locked lasers are the fundamental source of ultrashort and ultraintense light pulses and a principal pathway for three Nobel Prize technologies: optical frequency combs, chirped pulse amplification, and attosecond light pulses. They are essential in routine and high-level applications such as refractive surgery, spectroscopy, or metrology.
