IMPORTANT

   Due to recent problems with web server at c4r0.skrzynka.org address this website has been moved to a server provided by the elektroda.pl portal. The new address is c4r0.elektroda.eu. I placed redirection at the old address. I haven't moved the MySQL databade and I am not gonna make a new one, therefore the website statistics, guestbook and newsletter has been blocked.

   Regarding the future of this website: I am going to maintain the current contents on-line. There are also a few projects that I was going to work on and present here afterwards. Two most interesting are 445nm 1W laser diodes and an SSY-1 Nd:YAG laser. However, those new toys have been sitting in my drawer for more than a year and I have no time to work on it (I guess the time in my life when there are more important things has finally come...). Therefore, I'm not sure wether anything new will ever appear at this website (I hope so, though).

   Best regards to all who have visited this website frequently - it's all here for you.
