13:25:30	 Von  Colin : Clear for me
13:25:32	 Von  Max : it's clear
13:25:32	 Von  Álvaro Ramos Perez : For me it is clear too
13:25:35	 Von  Ho-Yun Lee : Clear
13:25:35	 Von  Loïc Rüegg : Same
13:38:43	 Von  Noé Duruz : thank you
13:38:43	 Von  Álvaro Ramos Perez : Okay
13:38:56	 Von  Loïc Rüegg : Yes t's better
13:38:56	 Von  Ho-Yun Lee : yes
13:38:57	 Von  Noé Duruz : yes keep the laser
13:40:50	 Von  Loïc Rüegg : It's the radius at the focal point ?
13:40:53	 Von  Loïc Rüegg : waist*
13:43:16	 Von  Noé Duruz : can you repeat the question
13:46:19	 Von  Max : yes
13:46:19	 Von  Álvaro Ramos Perez : yes
13:46:19	 Von  Colin : Yes
13:46:19	 Von  Ho-Yun Lee : yes
13:53:32	 Von  Noé Duruz : question
13:56:00	 Von  Noé Duruz : yes thank you
14:06:26	 Von  Loïc Rüegg : I didn't hear due to my connection but did you say fiber laser are the best for beam quality ?
14:25:01	 Von  Max : Are fiber laser "just" regular lasers with their output transported in optical fibers? 
14:28:41	 Von  Colin : Regarding optical fibers, wouldn't it be easier to just have a bigger core to prevent the need to focus the beam?
14:29:49	 Von  Max : Ok thank you
14:29:52	 Von  Max : yes perfect
14:31:06	 Von  Colin : Ok, makes sense
14:31:08	 Von  Colin : Yes
14:31:10	 Von  Colin : Thank you
14:37:57	 Von  Loïc Rüegg : yes
14:38:06	 Von  Vladimir Bourquin : yes
14:42:25	 Von  Ho-Yun Lee : Didn’t heard of this before
14:42:26	 Von  Loïc Rüegg : yes
14:42:29	 Von  Max : no glasses
14:42:49	 Von  Loïc Rüegg : Yes
14:43:39	 Von  Noé Duruz : Like a Bragg reflector ?
14:49:02	 Von  Noé Duruz : yes
14:49:03	 Von  Max : yes
14:49:06	 Von  Loïc Rüegg : yes
14:49:28	 Von  Patrik Hoffmann : What is the chromatic abberation of a Schwarzschild objective
14:49:28	 Von  Noé Duruz : waht is the aberation of a schwarzschild objective 
14:50:14	 Von  Loïc Rüegg : Are abbration a problem in general for microprocessing with laser ?
14:51:27	 Von  Loïc Rüegg : Ok thank you
14:52:19	 Von  Álvaro Ramos Perez : Thank you, but still the sound is not the best one
14:52:36	 Von  Loïc Rüegg : Are you using the wifi or a cable for the connection ?
14:52:56	 Von  Max : I think your band width isn't enough to have the shared screen + webcam
14:53:02	 Von  Loïc Rüegg : Yeah maybe with cable it's better
14:54:30	 Von  Max : thank you for the lecture!
14:54:32	 Von  Loïc Rüegg : Thank you ,have a nice day
14:54:39	 Von  Colin : Thank you, have a nice weekend
14:54:41	 Von  Max : you too
14:54:41	 Von  Ho-Yun Lee : Thank you
14:54:43	 Von  Max : bye
14:54:45	 Von  Álvaro Ramos Perez : Bye
