It is reported about the first observation and studying of the photon echo in LuLiF~4~:Er^3+^. The energy transition is ^4^I~15/2~โ^4^F~9/2~ (ฮป=6536 ร ). The density of ErF~3~ is 0.025 wt%. The operation temperature is 1.9 K. Measurements were spent at low (up to 1200 Oe) and even zero external magne
