Comparison of Continuous Wave and Ultrashort Pulsed Holmium-doped Fiber Lasers Exposure on Ex-vivo Tissue

Holmium (Ho 3+ ) laser systems emitting in the spectral range of 2-2.1m are widely used in many medical fields: urology, dermatology, surgery, and etc. This is due to the high absorption of laser radiation by water contained in soft tissues. It is of interest to compare the efficiency of soft tissue ablation using 2m lasers operating in continuous wave (CW) and ultrashort pulsed modes. In previous studies the Tm-doped fiber laser [1], Tm:YLF and Ho:YAG lasers [2] exposure have compared. © 2021 IEEE.
