  Laser technologies improved after the understanding of the Chirped Pulse
Amplification (CPA) which allows energetic laser beams to be compressed to tens
of femtosecond (fs) pulse durations and focused to few $\mu$m. Protons of tens
of MeV can be accelerated using for instance the Target Normal Sheath
Acceleration (TNSA) method and focused on secondary targets. In such
conditions, nuclear reactions can occur and radioisotopes relevant for medical
purposes be produced. High repetition lasers can be used to produce enough
isotopes for medical applications. This route is competitive to conventional
methods mostly based on accelerators. In this paper we study the production of
$^{67}$Cu, $^{63}$Zn, $^{18}$F and $^{11}$C currently used in positron emission
tomography (PET) and other applications. At the same time, we study the
reaction $^{10}$B(p,$\alpha$)$^{7}$Be and $^{70}$Zn(p,4n)$^{67}$Ga to put
further constraints to the proton distributions at different angles and to the
reaction $^{11}$B(p,$\alpha$)$^{8}$Be relevant for energy production. The
experiment was performed at the 1 petawatt (PW) laser facility at Vega III
located in Salamanca-Spain. Angular distributions of radioisotopes in the
forward (with respect to the laser direction) and backward directions were
measured using a High Purity Germanium Detector (HPGE). Our results are
reasonably reproduced by the numerical estimates following the approach of
Kimura et al. (NIMA637(2011)167)
