Description
Green laser sources are often used for fluorescence excitation, Raman scattering, as well as for Ti: sapphire pumping applications. High long-term power stability is ensured by TEC thermal stabilization, thermal and optical feedback.
Note:
In
optical systems with strong back-reflections (e.g. more than 10%), the
laser must be protected by using an optical isolator with at least 20 dB
isolation. Typical applications include interferometry, confocal
microscopy (especially working with reflective samples), etc. Failure to
comply with these requirements will render the warranty void for cases
of COD (Catastrophic Optical Damage) of laser diode facets.
