Microchips are extremely useful when studying sample sizes less than a milliliter in volume. Researchers from Massachusetts Institute of Technology and Georgia Institute of Technology both used microchips in conjunction with infrared diode lasers to conduct experiments on small-scale environments. The absorption spectrum of water dictated the wavelength choices made by the researchers. On one hand, negligible heating of the water (via absorption) was desired, so the wavelength was chosen away from an absorption peak of water. In the opposite scenario, the laser was utilized to heat up the liquid in the microchip. As such, the wavelength was aligned with a water absorption peak.

In both cases, the laser power delivered to the microchip was a crucial experimental parameter. In each case, the laser driver plays a role in the quality of the output.

The LD5CHA is a next-generation replacement for the PLD5K-CH specified in the Case Study.  The PTC5K-CH can also be paired with the LD5CHA for higher current control than available with the LDTC2/2 cited in the Case Study.
