The new Compass Yellow is a compact, all-solid-state laser delivering 20 mW of continuous-wave (CW) output at 561 nm in a diffraction-limited (TEM 00 ) beam.
This laser will meet a growing demand for yellow laser excitation in fluorescence-based bioinstrumentation applications such as confocal microscopy. The new Compass Yellow is based on Coherent's family of field-proven, diode-pumped Compass green lasers, with complete platform commonality. This shared platform simplifies the transition to yellow excitation for existing users of Compass green lasers.
The higher power, low-noise output, and field-proven reliability of the Compass family also make Compass Yellow an attractive alternative for instrument builders currently using other yellow laser sources, including solid-state and Kr+ ion lasers. (The reliability of the Compass design approach has been well established by more than 15,000 Compass lasers currently operating in the field.). Compass Yellow also incorporates the same intracavity frequency-doubling platform, but this time utilizing the less known Nd:YAG fundamental at 1122 nm for a final output at 561 nm. Consequently, Compass Yellow delivers all the Compass family advantages for OEM and research applications, including a small footprint, low power consumption and reduced thermal budgets for simplified integration and remote operation.
