SANTA CLARA, Calif., Aug. 21, 2012 — Two new Verdi G lasers from Coherent Inc. offer single-longitudinal-mode (SLM) output. The Verdi G SLM series lasers deliver a linewidth of <5 MHz, which corresponds to a coherence length of tens of meters. They are offered with a choice of 2 and 5 W of output power at 532 nm.
They are based on optically pumped semiconductor laser (OPSL) technology, which is characterized by low noise, high electrical efficiency, a small platform, high stability and reliability. Single-frequency OPSLs deliver mode-hop-free output over hours of continuous operation.
The lasers are targeted at applications where narrow linewidth and/or long coherence length are critical, such as interferometry and holography. They also are suitable for atom cooling and trapping.
