A laser microjet is usually a water-jet-guided laser during which a pulsed laser beam is coupled right into a small-pressure water jet. This can be used to complete laser slicing capabilities though using the h2o jet to guide the laser beam, much like an optical fiber, via complete inner reflection. https://devinpesgt.activosblog.com/35983837/cnc-machines-for-medical-applications-an-overview
