Detailed Notes on LBO Crystal

Blog Article

LBO is a superb NLO crystal for OPOs and OPAs using a extensively tunable wavelength range and significant powers. The unique Houses of sort I and type II phase matching in addition to the NCPM go away an enormous area while in the research and purposes of LBO's OPO and OPA.

Even if the crystal materials or coating isn't delicate to h2o, little h2o droplets may concentration laser radiation extra tightly than less than regular Procedure, and therefore damage the crystal substance.

Also, it might be remarkably desirable to work with a crystal materials which may be critically phase-matched at room temperature simply because noncritical period matching normally will involve the Procedure in the crystal within a temperature-stabilized crystal oven. Nevertheless, the feasibility of critical stage matching might be specified just for sufficiently higher peak powers.

Note that although the nominal intensity is beneath the nominal hurt threshold, there might be troubles because of fluctuations during the beam ability or regional depth (e.g., if a beam profile has “incredibly hot places�?, or as a consequence of isolated defects inside a crystal, which might be more sensitive in comparison to the typical crystal substance.

EKSMA Optics utilizes cookies to provide you with the greatest buying experience. For those who keep on to employ our expert services, We'll suppose that you simply conform to the usage of this sort of cookies.

A seed crystal, commonly a little LBO crystal, is slowly but surely dipped into your soften and pulled up in a managed amount even though currently being rotated to keep up uniform progress. Since the seed crystal is pulled up, it continually melts and solidifies to form a single crystal.

LBO crystal (Lithium triborate) is often a non-linear optical substance of option for frequency converting substantial electricity lasers with its adhering to primary options:

LBO is the initial choice for building doubler or tripler for lasers for instance Nd:YAG wherever high electrical power density, significant balance, and while Procedure are demanded. 

This cautiously curated temperature profile ensures that the combination solidifies in a uniform way, forming an individual crystal composition. A important facet of the Flux strategy is definitely the temperature gradient, which has a big effect on the size and good quality of your crystal. Making certain a steady temperature gradient is crucial for getting large, higher-high-quality LBO Crystals.

Diode pumped sound state lasers with frequency changing LBO are remarkably dependable, compact, and use much less energy than the normal lasers they often swap. In lots of situations there was no ideal or reasonably priced laser to carry out the functions that DPSS lasers have enabled.

g. 20 μm. The team velocity mismatch inside the thicker substrate materials may not issue, as being the nonlinear conversation takes position only in The skinny crystal. The substrate only serves to mechanically stabilize The skinny nonlinear crystal.

Characterization procedures are essential for comprehending the Houses and optimizing more info the overall performance of LBO nonlinear crystals in numerous applications.

Inside of a nutshell, LBO is actually a sport-shifting nonlinear optical crystal which is indispensable in these days’s optical landscape.
