Laser Modules at Specific Wavelengths:
561 nm Laser Modules:
Characteristics: Emit light in the yellow-green range, providing a
good balance between high visibility and low phototoxicity, making
them ideal for biological and biomedical applications.
Applications:
Optogenetics: Used to stimulate or inhibit specific neurons that are
genetically modified to respond to yellow-green light, such as the
activation of red-shifted opsins (e.g., ChrimsonR) or for dual-color
stimulation alongside other wavelengths.
Photoluminescence Microscopy: Suitable for exciting fluorophores like
Rhodamine, Alexa Fluor 568, and mCherry, allowing for high contrast
imaging and single-molecule detection.
Intravital Imaging: Used in live animal imaging, as the 561 nm
wavelength penetrates biological tissues effectively with minimal
damage, enabling the observation of dynamic processes within living
organisms.
Semiconductor Inspection: Used for inspecting semiconductor wafers,
particularly in detecting defects or inhomogeneities that fluoresce
when exposed to yellow-green light.

577 nm Laser Modules:
Characteristics: Emit light in the yellow region, close to the peak
absorption of certain photosensitive molecules, with excellent
visibility and minimal background interference in many biological
tissues.
Applications:
Optogenetics: Provides selective activation of optogenetic tools,
especially in cases where fine control of neuronal circuits is needed.
It can be used to activate specific proteins that respond to yellow
light, providing highly targeted stimulation.
Intravital Imaging: Useful for imaging in tissue environments with
high hemoglobin concentration, as the 577 nm wavelength is near the
absorption peak of hemoglobin but still transmits through tissues
effectively, allowing for clear imaging with minimal scattering.
Photoluminescence Microscopy: Enables excitation of a range of yellow
and orange fluorescent dyes, such as YFP (Yellow Fluorescent Protein),
and enhances contrast and signal-to-noise ratio in imaging
applications.
Semiconductor Inspection: Effective in identifying small-scale defects
in semiconductor materials by leveraging the wavelength's sensitivity
to specific materials' photoluminescent properties.

589 nm Laser Modules:
Characteristics: Emit light in the yellow-orange range, known for its
high visibility to the human eye and minimal absorption by biological
tissues.
Applications:
Optogenetics: Used for controlling neural activity with high precision
by targeting optogenetic proteins like red-shifted opsins or for
dual-color experiments in combination with other wavelengths. This
wavelength is particularly useful for opsins sensitive to
yellow-orange light, such as Jaws or halorhodopsins.
Intravital Imaging: Ideal for deep tissue imaging due to low
absorption and scattering in biological tissues, allowing for
visualization of structures and processes within living organisms with
minimal photodamage.
Photoluminescence Microscopy: Excites a range of orange-red
fluorophores (like DsRed, mOrange) effectively and is used in
applications requiring clear visualization of specific molecular
events at these wavelengths.
Semiconductor Inspection: Offers enhanced contrast in detecting
certain material properties, particularly in examining the
photoluminescence of specific defects or features within semiconductor
materials.
