Efficient Tm:YAG and Tm:LuAG lasers pumped by 681 nm tapered diodes
(OSA - The Optical Society, 2019)In this paper, we present highly efficient continuous-wave (cw) laser operation of Tm:YAG and Tm:LuAG lasers pumped by high-brightness red tapered diodes. The single-emitter tapered diode lasers (TDLs) provide up to 1 W ... -
Efficient Tm:YAG and Tm:LuAG lasers pumped by red tapered diodes
(Institute of Electrical and Electronics Engineers Inc., 2019)Eye-safe, diode-pumped all-solid-state lasers working in the 2 ?m region are favourable for many applications including remote sensing, medicine, and gas sensing. Tm-doped crystals such as Tm:YAG and Tm:LuAG are among the ... -
Widely-tunable dual-wavelength Tm:YLF, Tm:LuAG, and Tm:YAG lasers
(Institute of Electrical and Electronics Engineers Inc., 2019)Dual-wavelength operation of lasers are attractive for many applications such as coherent terahertz wave generation, ultrahigh pulse repetition rate creation by optical beating, and laser ranging. Several methods could be ... -
