Different active thickness of LGADs and probing the sensitive depth from front and backside are exploited, The sensors used in this study are as follows: BK UFSD3.2 W18 with C-enriched gain layer and with active thickness of 47 microns (2x2 array); HPK-P2 W36 (no C-enriched gain layer) with 50 microns of active thickness, 2x2 area); HPK-P1, Type 1.2 , 35 microns and CNM - sensor from Run9254 with active thickness of 70 microns. All types of sensors are irradiated at the fluence of 1.5e15 and 2,,5e15 neq/cm2. Femtosecond laser based SPA mortality study was manly focused on study of LGAD's stability because we tried to avoid fatal damage so that sensors can be subjected to the illuminated from the back side. Front illumination was performed on all considered sensors sensors. TPA mortality study was performed from both sides: front and back. The results are discussed as well as future plans,
