A watt-level singly resonant optical parametric oscillator (OPO) was developed using MgO:sPPLT. This device generates up to 1.59 W of single-frequency idler output, demonstrating efficient parametric conversion for tunable laser applications.

Area of Science:

  • Nonlinear Optics
  • Laser Physics
  • Materials Science

Background:

  • Optical parametric oscillators (OPOs) are crucial for generating tunable coherent light.
  • MgO:sPPLT (periodically poled stoichiometric lithium tantalate doped with magnesium oxide) is a nonlinear crystal with favorable properties for OPO applications.
  • Achieving watt-level, single-frequency output from OPOs remains a key goal in laser development.

Purpose of the Study:

  • To develop and characterize a watt-level, single-frequency, continuous-wave (cw) singly resonant optical parametric oscillator (SRO).
  • To investigate the performance of MgO:sPPLT in a compact ring resonator configuration.
  • To demonstrate tunable idler output over a broad spectral range.

Main Methods:

  • Utilized a frequency-doubled diode-pumped Nd:YVO(4) laser at 532 nm as the pump source.

    • Verified the influence of thermal lensing on idler output power.

    Conclusions:

    • The developed MgO:sPPLT-based SRO is capable of producing watt-level, single-frequency output.
    • The compact ring resonator design and optimized focusing contribute to a low oscillation threshold.
    • The device offers broad, tunable output, making it suitable for various spectroscopic and photonic applications.
