Definitions

  • the hybrid optical system (optical system) 10 includes a laser source 30 for generating a first laser 30a with a first wave length 1040 nm for a Stokes light (Stokes beam, Stokes pulse, a first light) 11 and a pump light (pump beam, pump pulse, second light) 12, a second laser 30b with a second wavelength 780 nm, an OCT light 13, and a probe light (probe beam, fourth light) 14.
  • One of preferable laser source 30 is a fiber laser.
  • the first laser 30a may include one to several hundred fS (femtosecond)-order pulses with tens to hundreds of mW.
  • the optical system 10 includes a pump light path (second optical path, pump unit) 22 that is configured to supply the pump light (second light) 12 with a second range R2 of wavelengths 1070 nm that is shorter than the first wavelength range (first range) R1 from the first laser 30a which is common to the Stokes light 11.
  • the optical system 10 includes a common optical path 28a that supplies the Stokes light 11 provided by the path 21 and the pump light 12 provided by path 22 to the optical I/O unit 25.
  • the optical path 21, 22, and 28a include necessary optical elements 32 such as filters, fibers, dichroic mirrors and prisms to configure each optical path. The same applies to the optical paths described below.
  • the probe light path 24 includes a time delay unit 24a that is configured to control a time difference between emission of the probe light (fourth light) 14 and emission of the pump light (second light) 12.
  • the time delay unit may have collimators and a motorized delay stage that can control the distance between the collimators. Time delay may be controlled by the laser control unit 58 in the controller 55.
  • the probe light path 24 can supply the probe light 14 with a time difference from the emitting of the pump light 12 for emitting to the target 5 via the optical I/O unit 25.
  • FIG. 14 depicts another embodiment of the probe light 14.
  • the probe pulse 14 may be generated and emitted prior to or at the same time of that of the Stokes light 11 and pump light 12 till the duration of vibration response.
  • a system 1 for using the CARS light and the OCT light comprises: (a) a first unit 21 that is configured to emit a first light 11 with a first range of wavelengths; (b) a second unit 22 that is configured to emit a second light 12 with a second range of wavelengths shorter than the first range; (c) a third unit 23 that is configured to emit a third light 13 with a third range of wavelengths shorter than the second range; (d) an optical unit 25 that is configured to coaxially output the first light 11, the second light 12, and the third light 13 to a target (sample) 5 and acquire a light from the target 5; (e) a reference unit 34 that is configured to split off a reference light 13r from the third light 13; (f) a selecting unit 28b that is configured to select a reflected light 15 of the third light and a CARS light 17 with a range of wavelengths at least partially overlapping the third range from the acquired light and the CARS light is generated by the first light and the second light at the target;
