Lasers and the Emerging Field of Optogenetics
Laserglow: Optogenetics - DPSS laser modules - fiber coupling available
The ability to control the activation of small groups of neurons with great precision has been a dream of neuroscientists for a very
long time. A new technique known as "optogenetics" (developed by Karl Deisseroth's team at Stanford University) allows for very selective activation of neurons by insertion of a gene into the target
cells which encodes for sensitivity to certain wavelengths of light. Using a laser as the stimulation light source provides a controlled
wavelength and pulsing behavior, and having fiber optics attached to the laser module allows for a convenient method of delivering the
light to a selected target site. Laserglow's blue, yellow, and green laser modules are currently being used for optogenetics research in
leading laboratories, as we can provide the necessary wavelengths with options such as enhanced power stability, low noise
amplitude, power adjustment and controllable pulse frequency/duty cycle. Our customers keep coming back for multiple lasers because we
offer quality lasers at a highly competitive price, so you can worry about your experiments rather than your lab budget.
Some of our most popular lasers which are currently being used for optogenetics research are listed below:
473 nm
LRS-0473: Best value, power up to 1.5 W
LLS-0473: Less than 1% optical noise (1-20 MHz), very stable output, power up to 500 mW
532 nm
LRS-0532: Best value, power up to 20 W
LLS-0532: Less than 1% optical noise (1-20 MHz), very stable output, power up to 500 mW
561 nm
LRS-0561: Best value, power up to 2 W
LLS-0561: Less than 1% optical noise (1-20 MHz), very stable output, power up to 100 mW
589 nm
LRS-0589: Best value, power up to 2.5 W
593.5 nm
LRS-0594: Best value, power up to 800 mW
LLS-0594: Less than 1% optical noise (1-20 MHz), very stable output, power up to 800 mW
Customization Options:
