41 Recent Advances in Tm-fibers for 2mm Wavelength 41
42 Absorption & Emission Cross Sections Pump Options for Tm-doped Fibers Gain Spectral Region Emission Absorption Wavelength (nm) Resonant pumping around 156nm is difficult to power scale with direct diode pumping (no high power/brightness pumps) 42
43 Absorption & Emission Cross Sections Pump Options for Tm-doped Fibers Gain Spectral Region Emission Absorption Wavelength (nm) Solution here is to pump with Er:Yb fiber laser which is in turn pumped by 9xx high brightness diodes (>4W output power demonstrated, IPG 27) 43
44 Absorption & Emission Cross Sections Pump Options for Tm-doped Fibers Gain Spectral Region Emission Absorption Wavelength (nm) However, the overall E-O the efficiency is low using this scheme 44
45 Historical Perspective on 79nm pumped Tm-fibers Increasing the Tm 3+ concentration decreases the ion-ion separation to enhance the 2 for 1 cross-relaxation process. Pumping at 79nm is attractive because of the compatibility with 88nm pump diode; however, the quantum efficiency needs to be improved to be practical 45
46 Historical Perspective on 79nm pumped Tm-fibers Increasing the Tm 3+ concentration decreases the ion-ion separation to enhance the 2 for 1 cross-relaxation process. Early work on power scaling efficient Tm-doped silica fibers attributed to Jackson et al. (Uni. Sydney, Aus) and Clarkson et al (ORC, Southampton, UK) 46
47 Historical Perspective on 79nm pumped Tm-fibers Increasing the Tm 3+ concentration decreases the ion-ion separation to enhance the 2 for 1 cross-relaxation process. Both groups recognized early on that optimizing the cross relaxation process in highly doped silica fibers could improve the efficiency of 79nm pumped fibers 47
48 Slope Efficiency (%) Improvements in Fiber Efficiency over the Years :1 limit Date To date >65% slope efficiency has been demonstrated for 79nm pumped fibers operating around 2mm, approaching the theoretical limit 48
49 Slope Efficiency (%) Improvements in Fiber Efficiency over the Years :1 limit Date Far exceeding the overall E-O efficiency of resonant pumped Tm-fiber systems 49
50 Number of modes Tm-doped LMA Fibers for Single Mode Beam Quality Pedestal Silica Cladding Index Profile Tm-doped Core.1.2 NA Much of the early high efficiency Tm-doped fibers were multimode because of the high NA (A. Carter et al., CLEO 27) 5
51 Number of modes Tm-doped LMA Fibers for Single Mode Beam Quality Pedestal Silica Cladding Index Profile Tm-doped Core.1.2 NA High Tm-doping levels coupled with high Al co-dopant levels would lead to an NA>.2 w.r.t. the silica cladding (A. Carter et al., CLEO 27) 51
52 Number of modes Tm-doped LMA Fibers for Single Mode Beam Quality Pedestal Silica Cladding Index Profile Tm-doped Core.1.2 NA By incorporating a pedestal layer around the Tm-doped core the effective NA is reduced to ~.1, reducing the mode content within the doped core (A. Carter et al., CLEO 27) 52
53 Number of modes Tm-doped LMA Fibers for Single Mode Beam Quality Pedestal Silica Cladding Index Profile Tm-doped Core.1.2 NA By reducing the NA of the core, large core fibers with good beam quality became possible (LMA fibers) (A. Carter et al., CLEO 27) 53
