Polarization-dependent YVO4 crystal Raman laser operation with 816 and 890 cm−1 shifts

Compact 589 nm yellow source generated by frequency‐doubling of passively Q‐switched Nd:YVO4 Raman laser

“…Nd:YVO 4 crystal using for self‐Raman operation has attracted increasing attention in recent years, which performs laser gain and Raman conversion functions simultaneously 1–4 . Through frequency doubling of its first Stokes wave is also an important approach to achieve yellow emission 5–7 with significant application in medical treatment, laser display, remote sensing and metrology 8–12 .…”

“…Nd:YVO 4 crystal using for self-Raman operation has attracted increasing attention in recent years, which performs laser gain and Raman conversion functions simultaneously. [1][2][3][4] Through frequency doubling of its first Stokes wave is also an important approach to achieve yellow emission [5][6][7] with significant application in medical treatment, laser display, remote sensing and metrology. [8][9][10][11][12] Especially for second harmonic generation (SHG) of the c-cut Nd:YVO 4 crystal Raman laser, it could achieve 589 nm yellow emission for potential sodium beacon application as its resonating with sodium D 2 spectrum line.…”
