The comparison with Eyeglasses is acceptable For the reason that substantial attain bandwidth will allow e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We current a twin-crystal Yb:KGW laserthat iscapable to function as a Q-switched oscillator with output energy up to 24 W and pulse size of 20 ns,or for a regenerative amplifier with output electric power up to 21 W and pulse period underneath 200 fs after compression of chirped pulses. Equally lasers have fantastic beam quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Show powerful peaks at 980 nm and 1030 nm, respectively, making sure successful Electricity conversion and large effectiveness in laser techniques.
Optical structure of a laser with direct pumping Along with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output on the radiation, WP is usually a half-wave plate, CL can be a collimating lens, FL is often a concentrating lens, AE is an active element produced from an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC is definitely the output mirror, and SAM is a semiconductor saturable-absorber mirror.
Adhesion Exam Compliant with MIL-C-675C military services specifications, an adhesion take a look at included implementing a tape that satisfies LT-ninety technical specs on to the lens film layer. The tape was affixed completely then taken off vertically. This technique was done 3 times, leading to no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and therefore are utilised as lasing materials to crank out ultrashort (~ one hundred-200 fs) significant electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser devices.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is usually a extraordinary product that performs a vital position in laser know-how. Its Principal perform would be to deliver ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
Request RP Photonics for any information regarding tungstate lasers, including femtosecond lasers and superior-electrical power lasers.
