TOPTICA Photonics AG
About This Product
■ Characteristics
・ Laser guide star for compensation optical
・ Excite sodium in the atmosphere at 589nm
・> 20W CW output power, <5MHz narrow line width
・ A low power version is also available for cooling sodium laser
・ First commercial sodium guide star laser for air compensation optical optical
・ Easy movements and enriched functions just to switch on
・ Re -amplifier for high -efficiency photon returning
・ Reliable achievements
A high -output guide star laser developed for control of compensation optical at the ground astronomy. The second hyperonic wave occurrence of a near -infrared DFB semiconductor laser with a continuous raman fiber amplifier is adopted as the basic technology. It is a groundbreaking laser light source that allows a high output of 20W or 5MHz at the same time in 589nm, an excitation wavelength of sodium.
For laser cooling applications, a low -output model (2W) based on the standard product, DL RFA SHG Pro, can be provided with a narrow line width of the sub MHz order. Many technical issues, such as high -term operation, seismic design, and reducing the effects of gravity, have been cleared, and a very stable operation has been realized under 589 nm / 22W conditions.
