This study demonstrates active mode locking in an optical parametric oscillator for the first time. This technique generates short optical pulses, paving the way for new laser technologies.

Area of Science:

  • Nonlinear optics
  • Laser physics
  • Quantum optics

Background:

  • Optical parametric oscillators (OPOs) are versatile sources of tunable coherent light.
  • Achieving pulsed operation in OPOs often requires complex mode-locking techniques.
  • Active mode locking offers a robust method for generating ultrashort optical pulses.

Purpose of the Study:

  • To demonstrate active mode locking in a doubly resonant optical parametric oscillator (OPO).
  • To investigate the generation of short optical pulses using an acousto-optic modulator in an OPO.

Main Methods:

  • An acousto-optic modulator was integrated into a nearly degenerate, doubly resonant OPO.
  • The OPO was constructed using periodically poled LiNbO3 and pumped by a Nd:YAG laser.
  • The modulation frequency was synchronized with the cavity's free spectral range (120 MHz).

Main Results:

  • Active mode locking was successfully achieved in the OPO.
  • A pulsed regime was observed with pulse durations as short as 700 picoseconds.
  • The results confirm the feasibility of active mode locking for OPO pulse generation.

Conclusions:

  • This work represents the first demonstration of active mode locking in an optical parametric oscillator.
  • The technique enables the generation of picosecond pulses from OPOs.
  • This advancement has implications for ultrafast optics and laser science.
