Abstract: A biological tissue analysis device to analyze biological tissue by laser induced breakdown spectroscopy comprises a laser generator (1, 2), a spectrometer module (7, 8, 12) and a control unit (5, 6). The laser generator (1, 2) is configured to provide laser beam pulses towards a biological target tissue. The control unit (5, 6) is connected to the laser generator (1, 2) and to the spectrometer module (7, 8, 12). The control unit (5, 6) is configured to operate the laser generator (1, 2) to provide at least one of the laser beam pulses as analysis pulse generating, at a laser pulse time, an analysis plasma comprising a reference element at least in a first excited state and in a second excited state. The spectrometer module (7, 8, 12) is configured to collect, at an acquisition time, emission light of the analysis plasma and to analyze emission lines in the collected emission light.

Abstract: A laser ablating device for cutting human or animal natural or artificial hard tissue includes: a cutting laser source adapted to provide a pulsed cutting laser beam lasing at a wavelength suitable for ablating the hard tissue; an imaging laser source adapted to provide an imaging laser beam covering a broadband spectral region; and a beam mixing structure and a movable scanner mirror positioned after the beam mixing structure. The beam mixing structure is adapted to redirect the cutting laser beam of the cutting laser source and/or the imaging laser beam of the imaging laser source such that an optical axis of the cutting laser beam is parallel to an optical axis of the imaging laser beam. The scanner mirror is arranged to direct the imaging laser beam and the cutting laser beam when having parallel optical axes.

Abstract: A laser source (101) comprises: (i) a first beam generating configuration (111, 112, 113) adapted to generate a pulsed primary ablating laser beam (162) with pulses having a first emission spectrum and a first temporal pulse width to ablate one type of tissue, (ii) a second beam generating configuration (121, 122, 123) adapted to generate a pulsed secondary ablating laser beam (163) with pulses having a second emission spectrum different from the first emission spectrum and a second temporal pulse width to ablate another type of tissue different than the one type of tissue ablated by the primary laser beam (162), (iii) a third beam generating configuration (121, 122, 123, 126) adapted to generate a pulsed analysis laser beam (161) with at least one pulse having a third emission spectrum and a third temporal pulse width shorter than the first temporal pulse width and shorter than the second temporal pulse width, and (iv) a beam directing optics (125) with beam aligning elements adapted to align the primary abl
