An investigation was made of a synchronously pumped pulsed LiF: F2- crystal laser. The pump radiation was provided by a neodymium phosphate glass laser operating under passive mode-locking conditions and generating pulses of 7 ps duration. The LiF: F2- laser generated 2 ps pulses tunable in the 1.10-1.22 μm range and the efficiency of the conversion process was 35%. Under the conditions of quasi-cw nanosecond pumping and active mode locking the LiF: F2- laser generated pulses of duration of the order of 400 ps.
