Efficient 1.9 μm monolithic micro-laser was realized in a 0.9-mm-thick Tm 3+ :NaLa(MoO 4 ) 2 microchip coated with cavity mirrors directly. End-pumped by a fiber-coupled quasi-continuous-wave 795 nm diode laser, an average output power of 140 mW was obtained when the average incident pump power was 340 mW. Slope efficiencies calculated with respect to incident and absorbed pump power were 42 and 60%, respectively. The spectra and spatial profiles of the monolithic Tm 3+ :NaLa(MoO 4 ) 2 micro-laser were also measured and analyzed.
