摘要：
This study concerns the attenuation of the incident power from a free-electron laser (FEL) in steps of up to two orders of magnitude, while maintaining optical beam geometry. We have developed and evaluated the properties of a FEL attenuation filter system, which can be attached and detached, with the position of the focusing lens and the target sample fixed. As a result, we have established that our FEL attenuation filter system enables two orders of magnitude of power control for infrared wavelengths between 5.5 and 6.5 mum. We conclude that the attenuation system is extremely useful for various FEL applications. (C) 2001 American Institute of Physics.
