HGO grows Pr:YLF laser crystals using Czochralski technology. Pr3+:YLF has been found as promising laser material for producing visible lasers directly and UV lasers through intracavity second-harmonic generation. Very few laser materials have the necessary properties for the realization of lasing in the visible spectral range. Trivalent praseodymium (Pr3+) is known to be an interesting laser ion for use with solid-state lasers in the visible spectral range because of its energy levels scheme, providing several transitions in the red (640 nm, 3P0 to 3F2), orange (607 nm, 3P0 to 3H6), green (523 nm, 3P0 to 3H5), and dark red (720 nm, 3P0 3F3+3F4) spectral regions.

Descriptions:

HGO grows Pr:YLF crystals Protactinium -doped Yttrium Lithium Fluoride crystals. Pr3+:YLF has been found as promising laser material for producing visible lasers directly and UV lasers through intracavity second-harmonic generation. Very few laser materials have the necessary properties for the realization of lasing in the visible spectral range.

Advantages:

1) High absorption and emission cross-sections(∼10-19cm2)

2) Good overlapping of the absorption band in the blue spectral region with the emission of the InGaN laser diodes and 2ω-OPSL

3) Diode-pumped solid-state lasers for precise and efficient processing of metals such as copper or gold, entertainment industry and science
