The DFB grating addition allows for dual wavelength emission from the QCL. A single-mode state and a harmonic comb state combine inside the cavity for a THz frequency comb. The device generates THz frequencies at room temperature without any external optical setup. This allows for a harmonic frequency comb at 3.0 THz with a range of 2.2 to 3.3 THz. With the single QCL dual wavelength emission, the THz comb is more stable than multiple sources. This devices enables a greater current dynamic range for harmonic comb operation, especially useful in spectroscopy applications. Two uses of QCL frequency combs demonstrated by researchers at Harvard University are also discussed.<\/p>\n<p>The QCLs operation state is highly dependent on the\u00a0injection current. Because the harmonic comb state is\u00a0accomplished with slightly more current than single-mode\u00a0state, it is crucial that the QCLs are properly and accurately\u00a0driven and have stable temperature control.\u00a0\u00a0Wavelength Electronics&#8217;\u00a0<a href=\"http:\/\/www.teamwavelength.com\/maintenance\/product\/qcl2000-laboratory-series-2000-ma-qcl-driver-instrument\/\" target=\"_blank\" rel=\"noopener noreferrer\">QCL2000 LAB<\/a>\u00a0QCL drivers provide the necessary\u00a0stability for harmonic frequency combs.\u00a0 Wavelength Electronics&#8217;\u00a0<a href=\"http:\/\/www.teamwavelength.com\/maintenance\/product\/ptc10k-ch-10a-temperature-controller-chassis\/\" target=\"_blank\" rel=\"noopener noreferrer\">PTC10K-CH\u00a0<\/a>temperature controller\u00a0has\u00a0temperature stability of less than 0.0012\u00baC which surpasses\u00a0the required temperature stability of less than 10 mK in the\u00a0experiment.\u00a0At Harvard University, both studies use Wavelength Electronics&#8217;\u00a0TC5 LAB\u00a0to control the\u00a0temperature of the QCLs with the same noise levels listed for the Northwestern\u00a0University study.<\/p>\n<p><a href=\"http:\/\/www.teamwavelength.com\/maintenance\/download\/applicationtechnotes\/cs-ldtc07.pdf\" class=\"mtli_attachment mtli_pdf\" target=\"_blank\" rel=\"noopener noreferrer\">Read the full case study.<\/a>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;65143&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; onclick=&#8221;custom_link&#8221; img_link_target=&#8221;_blank&#8221; link=&#8221;http:\/\/www.teamwavelength.com\/maintenance\/download\/applicationtechnotes\/cs-ldtc06.pdf&#8221;][vc_column_text css=&#8221;.vc_custom_1607467127201{margin-bottom: 0px !important;}&#8221;]\n<h4 class=\"null\"><em><a href=\"http:\/\/www.teamwavelength.com\/maintenance\/download\/applicationtechnotes\/cs-ldtc06.pdf\" class=\"mtli_attachment mtli_pdf\" target=\"_blank\" rel=\"noopener noreferrer\">CASE STUDY: Differential Absorption LiDAR for NASA Ozone Mapping Requires Wavelength&#8217;s LD15CHA and PTC for Optimum Sensitivity<\/a><\/em><\/h4>\n[\/vc_column_text][vc_column_text css=&#8221;.vc_custom_1607468152461{margin-bottom: 0px !important;}&#8221;]Knowing how much and where ozone is in our atmosphere is important to daily life on Earth.
