<p><strong>Title</strong>: Laser-field-free alignment and orientation of state-selected asymmetric top molecules
</p>
<p><strong>Abstract</strong>: With combined electrostatic and shaped laser fields with a slow turn on and rapid turn off, laser-field-free orientation of state-selected asymmetric top molecules with higher degrees of orientation has been achieved (left figure).&nbsp; It is confirmed that higher degrees of orientation is maintained in the laser-field-free condition for 5-10 ps (center figure).&nbsp; The observation of slow dephasing of molecular orientation ensures that we will be able to achieve laser-field-free three-dimensional orientation of state-selected asymmetric top molecules with elliptical polarization instead of linear polarization (right figure).&nbsp; These techniques will be very useful to various applications.
