摘要

Radial velocity (RV) surveys supported by high precision wavelength references (notably ThAr lamps and I2 cells) havesuccessfully identified hundreds of exoplanets; however, as the search for exoplanets moves to cooler, lower mass stars,the optimum wave band for observation for these objects moves into the near infrared (NIR) and new wavelengthstandards are required. To address this need we are following up our successful deployment of an H band(1.45-1.7μm)laser frequency comb based wavelength reference with a comb working in the Y and J bands (0.98-1.3μm). This combwill be optimized for use with a 50,000 resolution NIR spectrograph such as the Penn State Habitable Zone PlanetFinder. We present design and performance details of the current Y+J band comb.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
