“…1(a). Like in [15], we used the water suspension of the black pigment ink (InkTec Corporation [20]) in the cylindrical glass cuvette 3 with inner diameter D = 10 mm and height 2 mm; the cuvette bottom being formed by a glass plate, the upper liquid surface being free. The suspension is heated by the radiation of the semiconductor laser 1 (Wavespectrum, WSLD-808-003-C, wavelength in vacuum λ = 808 nm).…”

“…The suspension was formed by diluted black ink for jet printers and was heated by a moderately focused beam from a near-IR CW laser. As described in [15], the bubbles were formed around the ink particles due to the superheated water evaporation. Additionally, due to the relatively high absorption coefficient α = 0.6 cm -1 and to the great number of closely spaced heating centers, the water within the illuminated volume was also heated to rather high temperature.…”

“…For the majority of applications, the well-concentrated laser radiation supplies the most convenient means for the bubble formation and manipulation. In this view, the possibility of a sharply localized water heating near absorptive nanoparticles deserves a special interest [2,14,15]. Under conditions of a CW laser radiation, near-stationary regimes of bubble evolution permitting their detailed investigation and control are enabled.…”

“…In the present work, we describe another possibility for laser-induced controllable generation of microbubbles in water. Contrary to [15], the suspension was additionally diluted so that superheating of the nearest vicinity of a single pigment particle provided but a weak warming of the ambient water volume. In such conditions, microbubbles can still be generated around the absorbing pigment particles but they predominantly contain the air gases dissolved in water [14].…”

A method is described for the generation of micrometer-sized vapor-gas bubbles in a water suspension containing absorptive pigment nanoparticles. The diluted suspension (mean interparticle distance 20 μm) absorbs the continuous laser radiation (wavelength 808 nm), and each particle in the best illuminated volume (~10 × 10 × 200 μm) serves as a bubble-nucleation center. The suspension heating is inessential (several degrees above the room temperature) and the bubbles are formed mainly of the air gases dissolved in water. The bubbles can stably exist within or near the illuminated area where their location is governed by the competition between thermal and optical forces and can be controlled via the laser beam parameters. The method enables controllable creation, support, prescribed transportation, and destruction of the bubbles. This can be useful in applications aimed at precise sorting, transportation, and delivery of species in nano- and micro-engineering as well as for biomedical studies.

A New Mechanism of Light‐Induced Bubble Growth to Propel Microbubble Piston Engine

Radiation pressure refers to the momentum transfer of photons during light “particles” impacting a surface. The force is too small to drive microengines. Different from the classical radiation pressure, the indirect radiation pressure (Fm) is introduced, coming from the momentum change of light‐induced bubble expansion. Fm is shown to obey Fm ∼ (I·rb)2, behaving faster growth of indirect radiation pressure versus light intensity I and bubble radius rb. An effective bubble size range is identified for Fm to suppress other forces for bubble in liquid. The top laser irradiation on nanofluid is used in this experiment. A well‐defined bubble pulsating flow, being a new principle of bubble piston engine, is demonstrated. During pulse on (≈ns scale), Fm exceeding other forces generates an extremely large acceleration, which is three to four orders larger than the gravity acceleration, propelling the bubble traveling downward. During pulse off, the bubble is floating upward due to the nonexistence of Fm. In such a way, the piston engine sustains the oscillating ranges of 38–347 µm for bubble diameters and 2.7–457.9 µm for traveling distances of piston. This work is useful to manipulate bubble dynamics in solar energy systems, and can find various applications in optofluidics.
