NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.

Area of Science:

  • Laser physics
  • Nonlinear optics
  • Materials science

Background:

  • Optical parametric oscillators (OPOs) are crucial for generating tunable laser light.
  • Developing high-energy, compact OPOs is essential for advanced laser applications.
  • Picosecond Yb:fiber lasers offer a robust platform for pumping OPOs.

Purpose of the Study:

  • To report a high-energy optical parametric oscillator (OPO) synchronously pumped by a picosecond Yb:fiber laser.
  • To demonstrate the compact design and tunable output of the developed OPO system.
  • To characterize the output pulse energy and beam quality of the OPO.

Main Methods:

  • Utilized a Yb:fiber-amplified, picosecond, gain-switched laser diode operating at 7.19 MHz for synchronous pumping.
  • Employed a 42-m-long ring cavity with an intracavity optical fiber for a compact design.
  • Used a periodically poled MgO-doped LiNbO(3) crystal as the nonlinear medium within the OPO.

Main Results:

  • Achieved high output pulse energies of 0.49 μJ (signal at 1.5 μm) and 0.19 μJ (idler at 3.6 μm).
  • Demonstrated tunability of the signal from 1.5 to 1.7 μm and the idler from 2.9 to 3.6 μm.
  • Measured M(2) beam quality values of 1.5 × 1.3 for the signal and 2.8 × 1.9 for the idler at high power.

Conclusions:

  • The developed OPO system provides high-energy, tunable output in the infrared spectrum.
  • The compact ring cavity design incorporating an intracavity fiber is effective for high-performance OPOs.
  • The results highlight the potential of this Yb:fiber-pumped OPO for demanding laser applications.
