1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
2. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
3. Claims 1-15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by ZH et al. (CN 103779766, Cite No. 1 in Foreign Patent Doc. of IDS filed on 6/16/2023, here, English translated one in FIT database of PE2E Search).
Regarding claim 1, ZH et al. discloses in figure 1 and specification:
1. A Raman laser conversion device (see, Abstract) for generating a single longitudinal mode, SLM, laser output, comprising:
a Raman medium (see, 7, fig. 1, see also paragraph [0016]) that exhibits a Stokes emission when subject to pumping by a laser pump input, the laser pump input having a pump linewidth and the Raman medium having a Raman linewidth (see, paragraph [0016]); wherein
the Raman medium is configured to define feedback interfaces of a resonator such that the Stokes emission resonates within the Raman medium (see, paragraph [0012]-[0013]); and further wherein
the free spectral range, FSR, (see, paragraph [0016], here, he Raman light resonator longitudinal mode interval about 5 GHz) of the resonator with respect to the pump linewidth and/or the Raman linewidth or a function thereof is such that only one longitudinal mode of the Stokes emission is able to resonate within the Raman medium; whereby
the laser conversion device generates a SLM laser output that is frequency shifted with respect to the laser pump input (see, paragraph [0016], here, 1064 nm, 1197 nm).

Regarding claim 2, ZH et al. discloses in figure 1 and specification the device of claim 1, wherein the FSR of the resonator is greater than the pump linewidth (see, paragraph [0016], here, 6 GHz, 12 GHz).
Regarding claim 3, ZH et al. discloses in figure 1 and specification the device of claim 1, wherein the Raman medium is a diamond crystal (see, paragraph [0016], here, Raman gain crystal 7 selecting Ba (N03) 2 crystal).
Regarding claim 4, ZH et al. discloses in figure 1 and specification the device of claim 1, further comprising an actuator (see, paragraph [0016], here, the FP etalon 5)
configured to adjust at least one parameter of the resonator so as to adjust the frequency of the SLM laser output (see, paragraph [0016])
Regarding claim 5, ZH et al. discloses in figure 1 and specification the device of claim 4, wherein the actuator comprises means for adjusting the temperature of the Raman medium (see, paragraph [0016]).
Regarding claim 6, ZH et al. discloses in figure 1 and specification the device of claim 4, the actuator comprises one or more of: a pressure actuator; an acoustic wave generator; a magnetic field input; a voltage input; and a position controller configured to adjust the position of the Raman medium with respect to the laser pump input (see, paragraph [0016]).
Regarding claim 7, ZH et al. discloses in figure 1 and specification the device of claim 1, wherein at least one feedback interface comprises a feedback element that is configured to increase the feedback of the Stokes emission at that interface. (see, paragraph [0016]).
Regarding claim 8, ZH et al. discloses in figure 1 and specification the device of claim 1, further comprising a pump feedback element that is configured to feed back the pump laser input into the Raman medium (see, paragraph [0016]).
Regarding claim 9, ZH et al. discloses in figure 1 and specification the device of claim 1, herein the geometry of the Raman medium is configured to define an optical path length of the resonator for a particular resonator mode (see, paragraph [0016]).
Regarding claim 10, ZH et al. discloses in figure 1 and specification the device of claim 1, further comprising a second Raman medium coupled to the first Raman medium via a coupling feedback interface wherein the second Raman medium is configured to define feedback interfaces of a second resonator (see, paragraph [0016]).
Regarding claim 11, ZH et al. discloses in figure 1 and specification the device of claim 1, a Raman laser system for generating a single longitudinal mode, SLM, laser output, comprising: a pump laser configured to provide a laser pump input, the laser pump input having a pump linewidth; and a Raman laser conversion device according to claim 1, configured to receive the laser pump input (see, paragraph [0016]).
Regarding claim 12, ZH et al. discloses in figure 1 and specification the laser system according to claim 11, further comprising a focussing element (see, fig. 1 see also, paragraph [0012]) configured to focus the laser pump input into the Raman medium with an intensity great enough such that the device operates in the coherent Raman scattering regime.
Regarding claim 13, ZH et al. discloses in figure 1 and specification the laser system according to claim 12, further comprising a focussing element configured to focus the laser pump input into the Raman medium with an intensity great enough such that the device operates in the coherent Raman scattering regime (see, paragraph [0012]).
