In contrast to an ultrafast optical parametric oscillator, OPG does not require an oscillator cavity which is synchronized to the laser. However, the required pump intensities are much higher. For this reason, so far OPG experiments with ultrashort pulses have always required amplified pump sources, e.g. based on a mode-locked oscillator and a high-gain amplifier operated at a repetition rate of typically far below 1 MHz [1, 2]. Such pump sources lead to quite complex systems, and low repetition rates very much limit the obtainable average output power. Recent progress on high-power passively mode-locked all-solid-state lasers has enabled us to pump a parametric generator directly with a mode-locked laser, not using any amplifier system. In this way we obtained up to 0.5 W of average power in femtosecond pulses at 35 MHz repetition rate in the wavelength range of 1.38-1.56 μm using a periodically poled LiNbO3 (PPLN) crystal. The corresponding range of the idler is 3.03-4.06 μm.","PeriodicalId":376665,"journal":{"name":"Advanced Solid State Lasers","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122738866","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}

Possible applications of these lasers include medicine, remote sensing and trace gas analysis. Pulsed [2], continuous wave (cw) [3, 4], gain-switched [5] and diode-side-pumped laser operation [6] has been demonstrated with Cr2+:ZnSe, which exhibit slope efficiency as high as 63% and tunability between 2138 nm and 2760 nm. However, one of the problems encountered with this kind of materials is their relatively high level of passive losses at the laser wavelength. Thus both detailed spectroscopic studies including ESA measurements and synthesis of materials by using various crystal-growth techniques are necessary to estimate the amount of intrinsic optical losses and reduce as much as possible what is due to extrinsic reasons such as unwanted impurities and lattice defects. In this paper we report for the first time to our knowledge on the results of ESA measurements in Cr2+:ZnSe as well as on the realization of 1W efficient cw laser with Cr2+:ZnSe crystals.","PeriodicalId":376665,"journal":{"name":"Advanced Solid State Lasers","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122112011","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}
