The standard tuning elements indicated below are used in CW Ti:Sapphire
lasers such as
Trestles CW , Trestles fs/CW
as well as TIS-SF-777
Wavelength tuning:
Birefringent filter - thick
etalon - thin etalon
For CW Ti:Sapphire laser TRESTLES CW LH (Ti:Sapphire CW oscillator) which is
tunable in the range 700 - 1000 nm the
typical
linewidth is:
<45 GHz - with birefringent filter only - corresponds to 96
picometer at 800 nm
Below is an example of the calibration table showing relations between motot position and wavelength. As we can see one step corresponds to approximately 35 pm (picometers), that is 1/3 of the wavelenght which is 96 pm
| Position | Wavelength | Position change | Wavelength change | nm/step |
| 6233 | 864.4 | |||
| 8000 | 801.12 | 1767 | 63.28 | 0.035812 |
| 9000 | 766.28 | 1000 | 34.84 | 0.03484 |
| 10000 | 731.97 | 1000 | 34.31 | 0.03431 |
| 11000 | 697.66 | 1000 | 34.31 | 0.03431 |
More details on the tuning and calibration procedure can be found in the manual.
Tunable Titanium: Sapphire Continuous Wave Laser Trestles LH CW
Del Mar Photonics offers new
Trestle-LHs fs/CW laser system which can be easily
switched from femtosecond mode to CW and back.
Having both modes of operation in one system dramatically increase a number of
applications that the laser can be used for, and makes it an ideal tool for
scientific lab involved in multiple research projects.
Del Mar Photonics offers variety of continuum wave Ti:Sapphire lasers with linewidth from 45 GHz down to 5 kHz, output power from few hundred mW to 3 Watt. We also offer a combination of CW-femtosecond laser in one convinient to operate package.
Few example include Trestles CW , Trestles fs/CW as well as TIS-SF-777
