We report on the performance of two different laser configurations for high-power tunable thulium fiber lasers: one is a single oscillator utilizing a volume Bragg grating for wavelength stabilization; the other is a master oscillator power amplifier system with the We demonstrate the use of a bi-directional mode-locked thulium doped fiber ring laser as a single cavity free-running dual-comb source. The TFL has several Find your thulium fiber laser easily amongst the 9 products from the leading brands on DirectIndustry, the industry specialist for your professional purchases. V03-02 FIRST CLINICAL STUDY ON SUPERPULSE THULIUM FIBER LASER FOR LITHOTRIPSY. 1 and 1. Both q-switched and continuous-wave Tm fiber lasers have in the last few years been developed up to higher average powers.
Consequently, the Thulium fiber laser offers the potential for miniaturized next-generation ureteroscopy that may integrate remarkably thin fibers . When stimulated a crystal or a silica fiber doped with a rare metal from the Lanthanides series (Nd, Ho, Er, Tm) it emits a laser radiation in the infrared spectrum with high absorption in water. TFL parameters differ in several fundamental ways from Holmium laser, including smaller fiber delivery, more strongly absorbed wavelength, low pulse energy/high pulse rate operation, and more uniform temporal pulse structure. It has several properties that confer theoretical advantages over other lasers used for the same indication, such as technical versatility and a relatively small zone of thermal damage This system represents a new average power record for thulium-doped fiber lasers (1150 W uncompressed) and ultrashort pulse fiber lasers with diffraction-limited beam quality, in general, even considering single-channel ytterbium-doped fiber amplifiers. Thulium Fiber Laser listed as TFL.
Thulium Fiber Laser has unique qualities which make it perfect for a lot of different applications, namely, medicine, spectroscopy, laser ranging and micromachining of transparent materials, in particular, semiconductors and laser for LIDAR. Thulium Fiber Laser - How is Thulium Fiber Laser abbreviated? thulium-170; Thulium-Doped Fiber Special Warning: This unit is an industrial Laser with maximum output of 15W average, 10kW peak pulse. The ytterbium fiber laser has a wall plug efficiency of 16 to 20 percent. Word origin: Thulium is named for Thule, the earliest name for Scandinavia. 415W Single-Mode CW Thulium Fiber Laser in all-fiber format Abstract: High power Tm lasers at 2um region is a great source of interest for many application including optical pumping of hybrid (fiber-solid state) lasers, bio-medical, remote sensing and plastic welding.
5 cm polarization-maintaining fiber is demonstrated, which can operate with stable dual-wavelength lasing or tunable single All-fibre widely tunable thulium laser G. Treatment of Epilation-Related Postinflammatory Hyperpigmentation Using a 1,927-nm Thulium Fiber Fractional Laser. In this paper, we report a novel mid-IR OPO pumped by a pulsed thulium-doped fiber laser operating at 2-microns. The development of lasers Diode lasers are well suited for this mode of operation. However, the thulium-fiber laser, in this setting remains unstudied.
7 times) and dusting (x2 last generation thulium laser, unmatched in terms of efficiency, accuracy and safety in multiple surgical application fields. Thulium (Tm) is an excellent gain medium for 793 nm, 1180 nm, or 1550 nm pumping with emission at wavelengths above 1. org 48 | Page In the above equation 25 to 28, I is defined as the total lasing intensity in the doped fiber core, se is the Fiber Laser Efficiency Fiber Laser Efficiency. Highly thulium-doped silicate glass fibers can be used to develop single-frequency fiber lasers with 1. Abstract: We report the usage of chemical vapor deposition-grown monolayer WSe 2 as a saturable absorber (SA) for a mode-locked thulium-doped fiber laser.
Nufern also offers a range of NuMATCH passive fibers to easily construct fiber lasers and amplifiers by minimizing splicing losses between components. 74 Î¼m and mode suppression and Q-switched laser performance in thulium-doped large mode area and photonic crystal . Thulium fiber laser is, in general, better for CW operations, when holmium laser is preferred for pulsed and q-switched lasers operations because of its high gain. This study explores use of a short taper for expanding the Thulium fiber laser beam at the distal tip of a small-core fiber. 8 2.
