Gallate laser crystal preparation device

The invention relates to the technical field of laser crystal preparation, and discloses a gallate laser crystal preparation device which comprises a crucible, a lifting assembly and a first backflow assembly, the first backflow assembly comprises a collecting cover, a high-temperature scraper assembly and a backflow pipe, and the collecting cover is connected to the top end of the crucible and used for collecting condensed volatile matter; the high-temperature scraping plate assembly is connected with the lifting assembly and used for melting and scraping off volatile matter on the inner wall of the collecting cover, and the backflow pipe is arranged on one side of the crucible and used for guiding the scraped melting volatile matter into the laser crystal raw material at the bottom of the crucible. The high-temperature scraper assembly is adopted to scrape off volatile matters attached in the collecting cover, the volatile matters are in a molten state when making contact with the high-temperature scraper a
