We report on first nonlinear mirror mode-locked praseodymium based solid-state laser. As an active medium, the Pr:YAlO3 crystal was used. For mode-locking, a nonlinear BBO crystal together with a properly designed dichroic mirror were employed to form an output coupler with intensity dependent reflection. Using 1W InGaN pump laser diode, 22 mW of mean output power with pulse duration and repetition...
A ring optical parametrical oscillator generating counterpropagating trains of picosecond pulses at the wavelength 1540 nm was realized. Operation stability of the system was investigated.
We developed an intracavity synchronously pumped optical parametrical oscillator, generating two independent trains of picosecond pulses at wavelength 1540 nm. We have improved and optimized experimental setup from the point of view of achievability of stable mode‐locking and compensation of astigmatism. Present setup is as very little sensitive on the action of thermal lens generated in the Nd:YVO...
We improved experimental setup of intracavity synchronously pumped optical parametrical oscillator, generating two independent trains of picosecond pulses at wavelength 1540 nm. The influence of external conditions on dual pulse generation was studied.
A high conversion efficiency and stability are the anticipated advantages of intracavity pumped parametric oscillators, as opposed to the traditional externally pumped ones. The dynamics of the coupled pump and signal cavities, however, is very complex and poses a considerable design challenge. In this paper we present a simulation of an optical parametric oscillator, pumped intracavity by a mode-locked...
Experiments and simulation demonstrate an instability of the intracavity pumped optical parametric oscillator against bidirectional operation. It is shown that nonlinear losses inside the signal cavity can stabilize the bidirectional operation.
A picosecond pulse circulating inside a mode-locked vanadate laser, pumps twice/round-trip a LiNbO3 crystal, creating two non-interacting signal pulses circulating in a resonant cavity. This configuration is ideal for intracavity interferometry applications.
