The Bm/F# chord is a B minor chord, with the F# (the 5th) as the bass note.
The B minor chord itself has a dark, melancholy sound. Playing the 5th of the chord (in the case of Bm, the 5th is F#) as the bass note, can make the chord sound even more dark and dramatic, even if it is only a subtle difference.
The chord is also referred to as B minor over F#, or Bm ‘slash’ F#, or simply, B minor with an F sharp in the bass.
Technically, the B minor chord with the F# in the bass is a second inversion B minor chord.
