A laser system and components for generating Single-Longitudinal-Mode (SLM) nanosecond laser beam having a wavelength in the range from 760 nm to 790 nm. The cavity of laser system comprising a front cavity mirror, an Erbium and Ytterbium irons co-doped or Erbium iron doped gain medium, a saturable absorber for passively Q-switching, an apparatus for polarization and longitudinal cavity mode selection, an intra-cavity frequency doubling crystal and an output dichromatic cavity mirror. The cavity is optically pumped by a diode Laser pump source.
