2. Piezo-mounted Mirror Designed for high-frequency response, and providing a unity gain bandwidth in excess
of 40 kHz, the piezo-mounted mirror ensures a tight lock corresponding to a very
narrow linewidth.
3. Miniature Optical Diode This highly compact device ensures unidirectional operation over the entire tuning range.
4. Etalon A single, thin etalon ensures single-mode operation using an innovative servo-lock to
eliminate mode-hops.
5. Reference Cavity An Invar-spaced, high-finesse (>25) interferometer, held in a temperature-controlled
environment and sealed to resist pressure changes, provides good long-term stability
for the single-frequency laser. Locking to this cavity can achieve relative linewidths as
low as 10 kHz.
6. Galvanometer-mounted Twin Brewster plates enable scanning in excess of 40 GHz at 800 nm, without any
Tilting Brewster Plates resultant beam deviation.
7. Ti:Sapphire Selected, high figure-of-merit material provides a wide tuning range from 700 nm
to 1000 nm.
8. Birefringent Filter A low-insertion-loss, three-plate birefringent filter provides smooth tuning over a broad
tuning range.
9. Mirrors The entire tuning range is covered using the minimum number of laser mirrors, thus
reducing the need for time-consuming mirror changes. All mirrors use a threaded insert
system, ensuring ease and reproducibility of mirror replacement.
10. Output Couplers Optimum output couplings are chosen to suite the varying gain profile of Ti:Sapphire,
ensuring high output powers and overall efficiency throughout the tuning range.

Frequency-doubling Option The ultra-narrow linewidth performance of the MBR-110 Ti:Sapphire laser can be translated
(MBD-200) into the blue and near-UV (350-500 nm) region of the spectrum by using the MBD-200
Monolithic Block Frequency Doubler.

MBR-110 Ps (Passive Scan) Addition of intracavity Brewster plates to MBR-110 EL enables continuous scanning up
to 20 GHz.
Focusing Optics No external focusing optics are required when using any commercially available laser pump
(see footnote 1, back page).
MBR E-110 Electronic Laser By custom-designing the electronic locking system to match the characteristics of the
Servo-control Unit Ti:Sapphire ring laser, exceptionally narrow linewidths are achieved. This fully dedicated,
microprocessor-controlled unit is used to lock and control the single-frequency scan of the
laser. An LCD display and menu-driven software enable fast and efficient control of the
laser’s locking and scanning functions.
