The two pulsars are the radio-loud PSR J1907+0602 in the TeV pulsar wind nebula (PWN) MGRO J1908+06 and the radio-quiet PSR J1809-2332 in the `Taz' radio/X-ray PWN. These pulsars are relatively young and energetic and have been both detected in the X-rays by XMM-Newton, which makes them viable targets for optical observations. We observed the pulsar fields in the B and V bands with the Very Large Telescope (VLT) in 2015 June/July to search for their optical counterparts. Neither of the two pulsars has been detected down to 3σ limiting magnitudes of m<SUB>v</SUB> ∼ 26.9 and ∼27.6 for PSR J1907+0602 and PSR J1809-2332, respectively. We discuss these results in the framework of the multiwavelength emission properties of pulsars.STAMPAenArticle10.1093/mnras/stw22262-s2.0-85015083074000393566000051https://academic.oup.com/mnras/article/463/3/2932/26466292016MNRAS.463.2932MFIS/05 - ASTRONOMIA E ASTROFISICA
