An acousto-optic modelocker was used to initiate the pulse formation and pulses of 150fs duration were directly produced from both lasers when an intra-cavity two prism sequence was incorporated for cavity dispersion compensation.

The observation of self-mode-locking [2] has led to the realisation that the nonlinear refractive index of the laser medium can be used to provide both amplitude modulation, through self-focussing or \"Kerr Lens Mode-locking\" [3], and phase modulation which, together with group velocity dispersion, can lead to further pulse compression. These pulse compression mechanisms are not restricted to Ti:sapphire but will work with any nonlinear medium in the laser cavity [4], We present here the observation of sub-100 fs pulse generation for the first time from a Cr:LiSrAlF6 laser.","PeriodicalId":242710,"journal":{"name":"Eighth International Conference on Ultrafast Phenomena","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133788666","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}

Femtosecond Spectroscopy of Magneto-Excitons 磁激子飞秒光谱学

Chemla","doi":"10.1364/up.1992.wb4","DOIUrl":"https://doi.org/10.1364/up.1992.wb4","url":null,"abstract":"Recently, quasi-2D excitonic (X) effects have been investigated extensively in semiconductor quantum well (QW), resulting in fundamental advances in our understanding of the effects of dimensionality reduction from 3D to 2D on the optical response of semiconductors, and have lead to numerous new applications in optoelectronic [1]. Efforts to make new semiconductor structures where electronic states are further confined in quasi-0 or quasi-1 dimensions, have had only very limited success because of the difficulty of obtaining narrow size-distribution of defect free samples. However, electronic states strongly confined in all dimensions, in material of excellent uniformity and optical quality, can be obtained by immersing a high quality QW well in a perpendicular magnetic field [2,3]. In such a situation, the crystal band discontinuities confine the electronic states in the direction perpendicular to the QW. In the QW plane, in addition to the Coulomb potential, -e2/εor, the e-h pairs experience the confinement of the quadratic-potential, (eHr)2/8mc2, imposed by the magnetic field, H. The relative strength of two confining potentials is measured by the dimensionless parameter, λ = (ao/lc)2, where ao is the Bohr radius and lc = (c/eH)1/2 is the cyclotron radius. The e-h pairs then form magneto-excitons (MX), which extrapolate continuously between quasi-2D excitons (λ = 0) and quasi-0D Landau levels (λ → ∞).","PeriodicalId":242710,"journal":{"name":"Eighth International Conference on Ultrafast Phenomena","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117105602","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}
