摘要： A laser apparatus 1A includes a light source unit 10A and a light combining unit 21. The light source unit 10A outputs first laser light L1 and second laser light L2 having a wavelength different from that of the first laser light L1 to different optical paths. The light combining unit 21 is optically coupled to the light source unit 10A, and combines the first laser light L1 and the second laser light L2 to generate a burst pulse with a frequency according to a difference between the wavelength of the first laser light L1 and the wavelength of the second laser light L2. In the light source unit 10A, the wavelengths of the first laser light L1 and the second laser light L2 are set in advance or settable such that the frequency of the burst pulse is 1 GHz or more. Thus, a laser apparatus and a laser light generation method capable of generating a burst pulse having a high repetition frequency of 1 GHz or more are realized.

摘要： A mode-locked laser system operable at low temperature can include an annealed, frequency-conversion crystal and a housing to maintain an annealed condition of the crystal during standard operation at the low temperature. In one embodiment, the crystal can have an increased length. First beam shaping optics can be configured to focus a beam from a light source to an elliptical cross section at a beam waist located in or proximate to the crystal. A harmonic separation block can divide an output from the crystal into beams of different frequencies separated in space. In one embodiment, the mode-locked laser system can further include second beam shaping optics configured to convert an elliptical cross section of the desired frequency beam into a beam with a desired aspect ratio, such as a circular cross section.

摘要： A pulsed fiber generator is configured with a unidirectional ring waveguide configured to emit a train of pulses. The ring waveguide includes multiple fiber amplifiers, chirping fiber components coupled to respective outputs of first and second fiber amplifiers, and multiple spectral filters coupled to respective outputs of the chirping components. The filters have respective spectral band passes centered around different central wavelengths so as to provide leakage of light along the ring cavity in response to nonlinear processes induced in the ring cavity. The pulse generator operates at a preliminary stage during which it is configured to develop a pitch to a signal, and at a steady stage during which it is configured to output a train of pulses through an output coupler at most once per a single round trip of the signal.
