Our procedure for bovine melanosome preparation followed the method of Dontsov et al.,8 and these details can be found in our previous report.2 In this study, additional wavelengths were investigated, including coherent emissions at 800, 900, 975, 1064, and 1540 nm. In order to observe the microcavitation events after exposure, a microscope containing two beam paths was used, a technique thoroughly described by Schmidt et al.2 Although the OPO described in our previous publication is stable and can generate wavelengths out to 2400 nm, there was not enough energy per pulse to create the microcavitation events above 1200 nm. Therefore, multiple lasers were required at longer wavelengths to generate enough energy per pulse to create the cavitation event with increasing wavelength. Microcavitation events at 1540 nm were determined using emissions from a Megawatt (high-peak power) Er-glass laser (Hilton Head Island, South Carolina) with a custom Q-switch, designed by Taboda Research Instruments (San Antonio, Texas). This laser has a reasonably Gaussian spatial distribution, with 35-ns pulse duration and 3.5 J maximum energy per pulse.9 The experimental setup for the 1540-nm data required changes from our previous report. Figure 1 is a schematic of the laser system and components.
