摘要： A single-mode (SM) Green fiber laser is configured to operate in a Green spectral range in a continuous-wave (CW) or quasi-continuous-wave (QCW) mode. The Green laser is configured with a pump source, outputting narrow-linewidth pump light at a fundamental wavelength in one (1) micrometer spectral range, and a single-pass second harmonic generator (SHG), such as a nonlinear LBO crystal, frequency doubling the pump light to output Green light at a signal wavelength. The pump light source is configured to have a MOPFA configuration with a SM seed which emits the SM pump light with a linewidth narrower than 0.2 nm, and at least one ytterbium ("Yb") fiber amplifier receiving and amplifying the SM pump light at the fundamental wavelength while maintaining the linewidth narrower than 0.2 nm. The SM Green fiber laser operates with a wall plug efficiency between 15 % and 30% in a 510 - 540 nm signal wavelength range and a power range between about 50 W and kW-levels.

摘要： A broad line red light generator is configured with a single mode (SM) pulsed ytterbium (“Yb”) fiber laser pump source outputting pump light in a fundamental mode (“FM”) at a pump wavelength which is selected from a 1030-1120 nm wavelength range. The disclosed generator further includes a SM fiber Raman converter spliced to an output of the Yb fiber laser pump source. The Raman converter induces an “n” order frequency Stokes shift of the pump light to output the pump light at a Raman-shifted wavelength within 1220 and 1300 nm wavelength range with a broad spectral line of at least 10 nm. The disclosed light generator further has a single pass second harmonic generator (“SHG”) with a lithium triborate (“LBO”) nonlinear optical crystal having a spectral acceptance linewidth which is sufficient to cover the broad spectral line of the pump light. The SHG generates a SM pulsed broad-line red light with a broad spectral line of at least 4 nm.

摘要： A frequency converter for converting a single mode input beam at a fundamental frequency to an output beam at a converted frequency is configured with a plurality of spaced optical components defining a resonant cavity. The optical components shape the input beam with at least one beam waist in the cavity. The frequency converter further includes a non-linear crystal located within the cavity in either a divergent beam with a Rayleigh range smaller than a cavity round trip length so that a center of the crystal is spaced from the beam, waist along a beam path, or in a collimated beam with a Rayleigh range greater than the cavity round trip length

摘要： A method for converting the optical frequency of a single-mode, single-frequency laser source includes generating a linearly-polarized single-frequency seed laser signal at a fundamental frequency; amplifying the seed laser signal in an optical amplifier; coupling the amplified signal into an external cavity formed by at least two mirrors, one of the mirrors being installed on a piezo actuator; enhancing the coupled signal inside the external cavity by locking a resonance frequency of the cavity to the frequency of the seed laser by continuously adjusting the optical length of the cavity with the piezo actuator; and converting the frequency of the enhanced signal using a non-linear crystal placed in a beam path inside the cavity. A method for converting the optical frequency of a single-mode, single-frequency laser source, includes generating a linearly polarized single-frequency seed laser signal at a fundamental frequency, the seed laser being a diode laser configured to adjust the frequency in response to controllable pump current variations; amplifying the seed laser signal in an optical amplifier; coupling the amplified signal into an external cavity formed by at least two mirrors; enhancing the coupled signal inside the external cavity by locking the frequency of the diode seed laser to a resonance frequency of the cavity by continuously adjusting the pump current of the diode seed laser; and converting the frequency of the enhanced signal using a non-linear crystal placed in a beam path inside the cavity.
