Two identical laser discs (slabs) with a gradient concentration of active laser ions are fabricated from a single crystal boule along the crystal growth axis, and are inverted with respect to each other in order to compensate for the gradient concentration. Due to a larger cross-section coming from utting along the crystal growth axis, and coupled with using a crystal media instead of ceramic or glass, the TACE® design allows for superior operation in high power solid state lasers.
Twin Active Crystal Element
Features
- The Twin Active Crystal Element® (TACE®) design allows for the largest active area currently available in crystal laser media, up to 10 times larger than current designs
- Crystal laser media has no grains compared to ceramic laser media, where grain size ≈ 20 nm
- Crystal laser media has better thermal management compared to glass laser media
- The twin design results in an even amount of reflections
- The TACE® design has its foundations in the crystal manufacturing process
Benefits
- A larger active area allows for higher average and peak energy of a laser system
- Superior beam quality and Power Spectral Density (PSD) stability
- Higher repetition rates achievable
- Laser beam polarization management made simple
- Competitive costs to ceramics and glass laser elements
Applications
- Optical amplifiers within high power solid-state laser systems
- Scintillator and saturable absorber for large area beams
- Absorber or detector for large area beams
