This was possible by improving both the efficiency of the semiconductor material by about 1/3 to 70% and the heat removal capability of the heat sinks used. We arrived at diode lasers which need 150 A or more and require a more and more refined cooling setup, especially if a rather stable wavelength is required. A further ramp-up of power would only benefit fewer and fewer applications as many of them need just 40 W or less from a diode laser.","PeriodicalId":191925,"journal":{"name":"2009 High Power Diode Lasers and Systems Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132147723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For most applications a collimation of the fast axis is required. Proper bar alignment and control of bar smile allow collimation down to a bar to bar pitch of 400µm. Furthermore the available power density has been increased by the advent of bars with peak power of up to 500W per bar. At 940nm these stacks operate at very low currents of only ∼200A for 500W/bar. This low drive current strongly simplifies the power supply of the huge systems.","PeriodicalId":191925,"journal":{"name":"2009 High Power Diode Lasers and Systems Conference","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115748747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-power diode laser modules typically have a relatively broad spectral width of about 3 to 6nm. In addition the center wavelength shifts by changing the temperature and the driving current, which is obstructive for pumping applications with small absorption bandwidths. Wavelength stabilization of high-power diode laser modules is an important means for more efficient pumping of solid-state lasers with a narrow absorption bandwidth.","PeriodicalId":191925,"journal":{"name":"2009 High Power Diode Lasers and Systems Conference","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127577147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microstructuring of the fiber material allows access to properties unobtainable in the bulk. These include (a) the possibility to guide light in air (through photonic band-gap or low density of state effects) including spectral regions where the bulk is opaque; (b) single mode guidance over extended spectral ranges (referred to as endlessly single mode (ESM) guidance); (c) extended control of dispersion and (d) the fabrication of fibers with very much larger values of Numerical Aperture (NA) than possible using conventional fiber fabrication approaches. Furthermore these unique properties may be tailored to enhance wavelength generation in fibers through non-linear effects or in fibers containing rare-earth dopants. In the following sections we discuss recent progress in the design and fabrication of such fibers that exploit several of these opportunities.","PeriodicalId":191925,"journal":{"name":"2009 High Power Diode Lasers and Systems Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124388962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
