The LCW/SCW series of high-power laser modules for pulsed or continuous-wave (CW) applications offer pulsed, high-peak optical power that reaches up to 500 mW. The continuous-wave optical power operates up to 75 mW. The available wavelengths include the 850 nm, 1,310 nm, 1,490 nm, 1,550 nm, 1,625 nm and 1,650 nm. The laser modules are designed to meet optical test equipment market performance requirements and are available in hermetically sealed, laser-welded packages. Thermoelectric coolers (TECs), temperature-sensing thermistors and back-facet monitors also are packaging options for wavelength stability over a wide temperature range.
