Abstract: Compact laser systems are disclosed which include ultrafast laser sources in combination with nonlinear crystals or waveguides. In some implementations fiber based mid-IR sources producing very short pulses and/or mid-IR sources based on a mode locked fiber lasers are utilized. Some embodiments may include an infrared source with an amplifier system comprising, in combination, a Tm fiber amplifier and an Er fiber amplifier. A difference frequency generator receives outputs from the Er and/or Tm amplifier system, and generates an output comprising a difference frequency. Exemplary applications of the compact, high brightness mid-IR light sources include medical applications, spectroscopy, ranging, sensing and metrology.
