• Efficient broadband tunable lasing of SrMoO4:Tm3+ crystal under 1700 nm laser diode pumping was obtained.
• Negligible effect of (3H43F4, 3H63F4) cross-relaxation on 3F4 level population for Tm3+ doping up to 0.25 at.% was shown.
• 3H4 up-conversion under 1700-nm excitation was shown to originate from the phonon-assisted pump excited-state absorption.
Spectroscopic and laser properties of Tm3+ ions under 1700 nm excitation in SrMoO4 crystal are investigated. Negligible effect of cross-relaxation process (3H43F4, 3H63F4) on population of 3F4 level for thulium concentrations up to 0.25 at.% was demonstrated. Efficient lasing with slope efficiency up to 18% and broadband (over 100 nm) tuning at room temperature under 1700 nm diode pumping were obtained.
