“…Relatively small changes in the wavelength can cause dramatic changes in the effective range of the LIDAR system. A calculated atmospheric transmission spectrum around 2.022 µm is shown longer wavelength in comparison to YAG crystals [4,5]. Especially for Tm the free running laser wavelength in LuAG (2.023 µm) is closer to the optical transmission window than the wavelength in YAG (2.016 µm) [6].…”

In this paper we report on diode pumped single mode Tm:LuAG and Tm,Ho:LuAG lasers which are developed as master oscillators for an airborne LIDAR system. Using a new fourfold pump setup 51 mW of output power with a Tm(10%):LuAG laser were reached at room temperature. The Tm(10%),Ho(0.4%):LuAG laser proved to be more temperature sensitive than the Tm laser. 18 mW and 30 mW of single mode laser output could be achieved at room temperature and 0°C, respectively. In multi mode laser operation 130 mW output power at room temperature (slope efficiency 36%) were achieved.

“…There is another attractive feature of LuYAG crystals compared with LuAG when considered for laser-radar hosts in the 2 mm region [5,6]. The centre lasing wavelength of 2022.7 nm for Tm:LuYAG with x ¼ 0:5; i.e., Lu 1.5 Y 1.5 Al 5 O 12 , is longer than either 2020.3 nm of Tm:LuAG or 2013.3 nm of Tm:YAG [5].…”

“…Compositional tuning can also be used to produce a laser with a wavelength corresponding to an atmospheric transmission peak [50]. Reducing the loss gives the laser a longer range when propagating through the atmosphere.…”

NASA is engaged in monitoring the health of planet Earth and exploring the other planets. For the former, global measurements of critical Earth parameters including ice sheet thickness, greenhouse gases, oxygen, wind velocity, and aerosols, are required. Highly specialized lasers, sometimes at new laser wavelengths, are needed to measure these variables. There are three approaches for this laser development being pursued by NASA. First, rather than seeking new lasers employing an empirical approach, a quantum mechanical model is used to predict better new lasers. Second, where lasers exist but the wavelength is not quite right, a technique referred to as compositional tuning was developed. Third, innovative laser designs are devised to produce laser sources at the requisite wavelengths.Reminiscent of a stop light, the STOP laser produces the red, orange, and green from a single laser oscillator.
