The features of soliton and non-soliton mode-locking of Yb:LuAP laser were studied. Maximum average output power of 7W with pulse duration of 130fs and 28.1 % optical efficiency were obtained in soliton mode-locking regime. Average output power up to 12W with 2ps pulse duration and 38% optical efficiency obtained in nonsoliton mode-locking regime. Chirped pulse regenerative amplifier based on Yb:LuAP crystal was investigated. Pulse duration as short as 165fs with output power of 4.5W at 200kHz pulse repetition frequency were demonstrated.","PeriodicalId":6789,"journal":{"name":"2021 Photonics North (PN)","volume":"39 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75603687","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}

The classification learning is done with the regression-based machine learning models. This system works as the pupil function predictor for the generated hologram. The training is done with the given dataset for different types of pupil functions. The extracted features of the hologram determine the model prediction for pupils used and then classification of OTF is performed. The accuracy measure for different learning algorithms has been analyzed and the Ensemble Adaboost classification algorithm shows best accuracy results for the prediction of the pupils used in OSH.

We propose to use a recently demonstrated powerful alternative technique of XUV generation, based on the high-order parametric processes.
