| 0:00:03 | welcome to this meeting or abstract on direct perks data creation by tonal ionisation |
|---|
| 0:00:09 | when a strong lay samples is applied to an optimal yet a nickel potential is |
|---|
| 0:00:14 | to sit and than electronic internal through the potential barrier |
|---|
| 0:00:19 | then it doesn't relates in the laser field until the laser pulse has passed |
|---|
| 0:00:23 | in the third step the electron can either escape the parent ion |
|---|
| 0:00:28 | it can be called in the boundary breaks state or the electronic and recall database |
|---|
| 0:00:33 | parent i in |
|---|
| 0:00:34 | resulting in a number of important phenomena |
|---|
| 0:00:37 | most notably high harmonic generation |
|---|
| 0:00:41 | both the number of feedback state and the number of high harmonic generation events |
|---|
| 0:00:45 | strongly decline with increasing ellipticity of the laser |
|---|
| 0:00:50 | while both processes show similar dynamics transfers to the electric field |
|---|
| 0:00:55 | explaining similar dependence on ellipticity |
|---|
| 0:00:59 | they have different dynamics longitudinal to lace if you |
|---|
| 0:01:03 | because the ionisation occurs in different parts of the optical cycle |
|---|
| 0:01:08 | neglecting the and fuels during the poles |
|---|
| 0:01:10 | the electron trajectory in the laser field can be approximated analytically |
|---|
| 0:01:16 | of the laser pulse |
|---|
| 0:01:18 | the electron has gained transverse thrift velocity which depends on ellipticity |
|---|
| 0:01:24 | we showed that the kinetic energy of rate per collections at the end of the |
|---|
| 0:01:28 | laser poles must be very small |
|---|
| 0:01:30 | this means the initial transverse velocity at the tonal accent |
|---|
| 0:01:34 | and the final drift velocity must cancel each other out |
|---|
| 0:01:39 | this is effective constraint on the initial condition of the electrons immediately after total ionisation |
|---|
| 0:01:46 | the coloured regions show initial conditions of ionisation face transverse velocity for which electrons and |
|---|
| 0:01:52 | up into a perk states |
|---|
| 0:01:54 | depending on the ellipticity |
|---|
| 0:01:56 | the transpose velocity enough to tunnel tiny station has a gaussian distribution |
|---|
| 0:02:02 | using this distribution we show that the required fields displays a gaussian dependence on electricity |
|---|
| 0:02:07 | as well |
|---|
| 0:02:09 | comparing experimental data with monte-carlo simulations |
|---|
| 0:02:13 | and is derived analytical formula |
|---|
| 0:02:16 | the very good agreement is found |
|---|
| 0:02:18 | we simulated the trajectory of electrons during the laser pulse enough to |
|---|
| 0:02:23 | taking account both the laser field and ti and potential |
|---|
| 0:02:28 | first the electron also late in the lace a few along the right trajectory |
|---|
| 0:02:33 | once the laser poses polished |
|---|
| 0:02:36 | it stays |
|---|
| 0:02:37 | on an elliptic lower bit as expected |
|---|
| 0:02:40 | that's one always stays relatively far away from the onion |
|---|
| 0:02:44 | its closest point is that l x it |
|---|
| 0:02:48 | this is in fact the typical behavior for a perk trajectories |
|---|
| 0:02:52 | at least eighty percent of all of it broke electrons obeys to further we then |
|---|
| 0:02:57 | there exits radius stylization |
|---|
| 0:03:00 | looking at the face of the field at the moment of ionisation this revealed that |
|---|
| 0:03:05 | repair guy electrons alright nice to predominantly before the peak therefore don't not three scatter |
|---|
| 0:03:12 | in contrast elections involved in high harmonic generation or ionised off to the peak of |
|---|
| 0:03:19 | the electric field and therefore come back to the parent ion |
