Additionally, the absorption spectra of water varies drastically in the infrared, and the researchers used that to their advantage. In both cases, the laser power delivered to the microchip was a crucial experimental parameter. In [1], the power needed to be well-controlled to ensure the viability of the cells being removed. In [2], the delivered power directly impacts the results of the PCR, since PCR requires specific temperatures for each phase. In each case, the laser driver plays a role in the quality of the output. Wavelength's LDTC2/2 utilizes the WLD3343 laser driver, which has 200 ppm stability, and was used to drive the cell-removal laser. The PLD5K-CH drove the infrared laser used to thermal cycle the PCR microchip. The PLD has <100 ppm stability, allowing precision power output of the infrared laser. For the cell-removal experiment, the WTC3243 is used for temperature control. The WTC allows for temperature control on the order of 0.009°C. This stability minimized wavelength fluctuations. This data is summarized below, in Table 1. EXPERIMENT CONTROLLER STABILITY Cell Removal LDTC2/2 200 ppm (laser) 0.009°C (temperature) PCR PLD5K-CH <100 ppm
