We are develop an In+ ion optical frequency standards based on an In+ sympathetically-cooled with Ca+ ions. It is expected to achieve a frequency uncertainty of 10-18. The 1S0-3P0 transition at 237 nm is used as clock transition, and 1S0-3P1 transition at 230 nm is used to detect the clock transition. We shall report how to produce the laser sources of 230 nm and 237 nm and laser frequency stability.
