Where to Buy Saturable Absorbers

Saturable absorbers are crucial components in the passive Q switching and mode locking of lasers. For Q switching, doped crystals like Cr4+:YAG or V3+:YAG are commonly used. In mode locking, semiconductor absorbers (SESAMs) are preferred due to their precise control over laser dynamics. These absorbers are essential in producing ultrafast laser pulses and maintaining stable laser operation.

saturable absorbers

Shalom EO offers a series of passive Q-switch crystals including Cr4+:YAG crystals, Co2+:MgAl2O4 (Co2+:spinel) crystals and V3+:YAG crystals. Cr4+:YAG crystals work well in Nd:YAG lasers, while Co:MgAl2O4 (or Co:spinel) crystals are suitable for erbium lasers and V3+:YAG crystals are a good choice for 1.3-μm lasers.

saturable absorbers

Our saturable absorbers are semiconductor-based mirrors (SESAM, SEmiconductor Saturable Absorber Mirror). In contrast to bulk absorbers, SESAMs offer low saturation fluences and fast relaxation dynamics. Reflekron offers customized SESAMs for laser systems along a wide wavelength range of 620 nm to 3.5 µm, for both mode-locked and Q-switched lasers.

Contact us for the optimal customized SESAM for your application.

ALPHALAS offers Cr4+:YAG, V3+:YAG and Co-spinel (Co2+:MgAl2O4) saturable absorber crystals for passive Q-switching of lasers with wavelengths in the range of 900 … 1100 nm and 1200 … 1600 nm. Different apertures and thicknesses as well as AR-coatings are available from stock and upon request. A special product group is our Brewster-cut Cr4+:YAG crystals for very high peak power applications and serving as a polarizer inside the laser cavity.

saturable absorbers

Optogama offers Co:MgAl2O4, Cr:YAG and V:YAG passive Q-switch crystals.

Co:MgAl2O4 (Co:spinel) is a very efficient passive Q-switch for lasers emitting in the range of 1.2 µm–1.6 µm due to good mechanical and optical properties.

Co:dpinel has a high absorption cross-section, which permits Q-switch operation of Er:glass laser (both flash-lamp and diode-laser pumped) without an intracavity focusing. Negligible excited-state absorption results in a high contrast Q-switch operation. Cr4+:YAG crystals are ideal for passive Q-switch operation of Nd:YAG and other Nd- or Yb-lasers emitting in the wavelength range from 900 nm to 1200 nm. A remarkable feature of Cr4+:YAG is the high damage threshold of >10 J/cm2 at 1064 nm, 10 ns.
