Over 300 pulsars are seen to pulse in GeV gamma rays acquired with the Large Area Telescope (LAT) on the Fermi satellite.
Many more may be waiting for discovery: of the >2000 LAT sources with no counterpart known at other wavelengths, hundreds are non-variable, with pulsar-like spectral shapes and sky distributions.
In addition, population syntheses typically predict as many as twice the current LAT pulsar sample.
However, detecting gamma-ray pulsations will be difficult for most of the new ones, whether through blind searches of the gamma-ray data, or using long-term phase-connected rotation ephemeredes for radio pulsars.
I will describe the sample of gamma-ray pulsars in the 3rd LAT Pulsar Catalog, and the ongoing work to transform candidates into discoveries. I will focus on the opportunities that FAST provides to identify the radio-faint,
gamma-loud pulsars hidden in the LAT data, highlighting some of the science that further discoveries enable.
