Diode-pumped room-temperature continuous wave Tm³⁺doped Lu₂SiO₅laser

Abstract

Abstract:We report on room-temperature laser actions of a novel thulium-doped crystal Tm:Lu2SiO5 (LSO) under diode pumping. An optical-optical conversion efficiency of 12% and a slope efficiency of 21% were obtained with the maximum continuous-wave (CW) output power of 0.67 W. The emission wavelengths of Tm:LSO laser were centered at 2058.4 nm with bandwidth of ∼ 13.6 nm. Absorbed pump power, W

Diode-pumped injection-seeded Tm,Ho:GdVO4laser

“…The resonator consists of three plane mirrors and one curved mirror. M1 and M2 are high-reflectivity flat mirrors; M3 is The dimension of Tm,Ho:GdVO 4 crystal used in the power oscillator is 4×4×7 mm 3 . The doped concentration of Tm is 5% and Ho is 0.5%.…”

Continuous-wave and actively Q-switched Nd:LSO crystal lasers

“…In recent years, many studies have been conducted on rare earth doped LSO as laser material. e.g., Yb:LSO [1][2][3][4][5], Tm:LSO [6], Ho:LSO [7,8], and Dy:LSO [9]. One of the main advantages is that this monoclinic biaxial crystal has strong natural birefringence which overwhelms the thermally induced stress birefringence [8].…”

Experimental investigation of the pulse width of a diode-pumped acousto-optically Q-switched Tm:YAG laser

“…Single-doped Tm 3+ lasers operating at 2 μm have attracted much attention for numerous applications ranging from remote sensing and medicine to laser radars [1][2][3][4][5][6][7]. Many Tm 3+ -doped laser media have been used for obtaining high-power 2 μm laser output in a diode-end-pumped configuration.…”
