The comparison with glasses is appropriate since the substantial obtain bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.

We current a dual-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output electric power nearly 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output electric power as many as 21 W and pulse length below two hundred fs just after compression of chirped pulses. Both of those lasers have fantastic beam high-quality with beam parameter M2

The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, guaranteeing economical Electrical power conversion and high efficiency in laser techniques.

Optical layout of a laser with direct pumping Using the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output in the radiation, WP is a 50 %-wave plate, CL is a collimating lens, FL is often a focusing lens, AE is an Lively factor comprised of an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC will be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.

Adhesion Take a look at Compliant with MIL-C-675C military services expectations, an adhesion take a look at associated implementing a tape that satisfies LT-ninety specifications onto the lens film layer. The tape was affixed completely then taken off vertically. This course of action was executed 3 times, leading to no blistering or peeling.

By publishing the data, you give your consent for the potential publication of the inputs on our website In accordance with our rules. (In case you afterwards retract your consent, we will delete People inputs.) As your inputs are to start with reviewed from the writer, They might be released with a few hold off.

Spatial construction with the beam plus the corresponding intensity profiles I on the output in the laser.

For tungstates, the ytterbium doping focus can be very substantial without major quenching since the replaced ions have an exceedingly comparable ion radius, plus the inter-ion length is relatively huge.

Nonetheless, after Nd3+:YAG grew more info to become commercially offered, the curiosity in CaWO4 dropped sharply. In afterwards yrs, particular other tungstate crystals started to attract lots of awareness.

The thermal conductivity of widespread double tungstates is from the get to 3–four W/(K m) �?which isn't undesirable compared with other laser crystals (Despite the fact that a number of periods lower than for YAG), and rather big when compared Using the thermal conductivity of normal Eyeglasses.

There isn't any things with your cart. Insert merchandise to your cart and ask for an Formal estimate or buy on the web Subtotal

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is really a exceptional materials that performs a very important job in laser technological know-how. Its Principal perform is to deliver ultrashort pulses of light, spanning just a few hundred femtoseconds.

Question RP Photonics for any information regarding tungstate lasers, including femtosecond lasers and significant-energy lasers.
