N2 - A new laser microscope (LM) has been designed and developed for in situ observation of metallic glass thin films and their interfaces with oxides. It can operate at various gas pressure and temperature conditions, from UHV(1×10-8Torr) to atmosphere and from RT to 1000°C, respectively. The LM system can be connected with a pulsed laser deposition (PLD) system that allows us to directly transfer the sample prepared in the PLD to the LM system without exposing it to air. In order to verify the capability of this LM system, the surface morphology of metallic glass thin films was characterized at various temperature and atmospheric conditions. As a consequence, we succeeded in making the first observation of the dynamic behavior of a metallic glass in liquid droplet form, and also found different behavior of transitions in vacuum.
