Temperature profiles of calyceal irrigation fluids during flexible ureteroscopic Ho:YAG laser lithotripsy

Jingfei Teng et al.

Summary: This study evaluated the changes in calyceal irrigation fluid temperature during flexible ureteroscopic Ho:YAG laser lithotripsy. Results showed that with sufficient irrigation, temperatures can be controlled to prevent a toxic thermal dose, but without irrigation, temperatures increased rapidly and reached 43 degrees C within seconds.

202 W dual-end-pumped Tm:YLF laser with a VBG as an output coupler

Disheng Wei et al.

Summary: In this study, a 202W Tm:YLF slab laser was demonstrated using a reflecting volume Bragg grating (VBG) as an output coupler at room temperature. Two active heat dissipation methods were employed to suppress wavelength shift. The highest continuous wave output power achieved was 202W with corresponding slope efficiency of 39.7% and optical-to-optical conversion efficiency of 36.5%.
