"Laissez-moi me concentrer pour cette expérience."

Translation: Let me concentrate for this experiment.

[qwUL3]

In English, it is more usual to say "concentrate ON" than "concentrate FOR"

[Stebnyk113]

Why not 'Laisse moi...'

[Mich59175m]

"Laissez-moi" is the imperative form.

[PaulFuller17]

Absolutely agree in English it's 'on' not 'for'.
