Double Side Polished Co2+:MgAl2O4 Single Crystal Substrate
Co2+:MgAl2O4 is a relatively new material for passive Q-switching
in lasers emitting from 1.2 to 1.6 μm, in particular, for eye-safe
1.54 μm Er:glass laser, but also works at 1.44 μm and 1.34 μm
wavelengths.
High absorption cross section (3.5×10-19 cm2) permits Q-switching
of Er:glass laser without intracavity focusing both with flash-lamp
and diode-laser pumping. Negligible excited-state absorption
results in high contrast of Q-switch, i.e. the ratio of initial
(small signal) to saturated absorption is higher than 10.
● Suitable for 1.54μm eye-safe lasers
● High absorption section and no excited state absorption

Co2+:MgAl2O4 Single Crystal Substrate Brief Introduction:
- Co2+:MgAl2O4 (Co2+:Spinel or Co:MALO) crystals is a new material for passive
Q-switching in lasers emitting from 1.2 to 1.6 µm, in particular,
for eye-safe 1.54 µm Er:glass laser, but also works at 1.44 µm and
1.34 µm wavelengths.
- High absorption cross section (3.5 × 10-19cm2) permits Q-switching
of Er:glass laser without intracavity focusing both with flash-lamp
and diode-laser pumping.
- Negligible excited-state absorption results in high contrast of
Q-switch, i.e. the ratio of initial (small signal) to saturated
absorption is higher than 10.
- We offer the high quality Co:Spinel crystals materials with high optical quality and uniform distribution of
Co2+ in laser grade polishing and coatings.
Co2+:MgAl2O4 Feature:
- Suitable for 1540 nm eye-safe lasers
- High absorption section
- Negligible excited state absorptio
- High optical quality
- Uniformly distributed Co
