Tips for preparing a search:. Keep it simple - don't use too many different parameters. Separate search groups with parentheses and Booleans. Note the Boolean sign must be in upper-case.
Example: (diode OR solid-state) AND laser search contains 'diode' or 'solid-state' and laser. Example: (photons AND downconversion) - pump search contains both 'photons' and 'downconversion' but not 'pump'. Improve efficiency in your search by using wildcards.
Asterisk (. ) - Example: 'elect.' retrieves documents containing 'electron,' 'electronic,' and 'electricity'. Question mark (?) - Example: 'gr?y' retrieves documents containing 'grey' or 'gray'. Use quotation marks ' ' around specific phrases where you want the entire phrase only. For best results, use the separate Authors field to search for author names.
Author name searching:. Use these formats for best results: Smith or J Smith. Use a comma to separate multiple people: J Smith, RL Jones, Macarthur. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored. Abstract An external-cavity Raman laser with a BaWO 4 crystal is reported to generate a high-brightness, mid-infrared output at 2.6 μm.
An actively Q-switched Ho:YAG laser at 2.097 μm is used as the pump source. The first Stokes output from the Raman laser reached 1.35 W with a near-diffraction-limited beam quality. Pulse widths as short as 8.5 ns are measured at a repetition rate of 5 kHz. Maximum conversion efficiency with respect to the incident pump power is measured as 14%. This simplified external-cavity configuration facilitates the realization of Raman-shifted sources within the water absorption window, using fixed and tunable Tm- and Ho-doped solid-state and fiber lasers.
