Abstract
Methods and systems for sterilizing a room are disclosed, including using a laser to generate a pulsed laser beam; using a robotic arm to direct the pulsed laser beam to a scattering optical element and to change the position of the scattering optical element; and using the scattering optical element to substantially isotropically scatter the radiation of the pulsed laser beam to sterilize the room. The scattering optical element comprises a hollow fused silica bulb filled with solid fused silica spheres or a fiber optic bundle and in some embodiments the scattering optical element is rotated. The pulsed laser beam comprises a wavelength ranging between about 200 nm to about 320 nm and in some embodiments comprises nanosecond or picosecond light pulses. Other embodiments are described and claimed.
