THE SMART TRICK OF LASER CRYSTAL THAT NO ONE IS DISCUSSING

Noticeable strong-state lasers based upon laser crystals are compact and light. Lasers from deep red to blue are already documented. In particular, there have been many studies on Pr3+ doped laser crystals, and continuous wave lasers around 490 nm are achieved. Ti∶sapphire is the main attain crystal for ultrafast lasers. Superintense ultrafast la
