Latest Patents
One of Gunnar's latest patents is for a Frequency Stabilized Laser Source. This innovative laser arrangement utilizes a Lyot filter to achieve single mode operation. The design includes a birefringent element with a cavity folding mirror and a polarizing element, which improves the free spectral range of the Lyot filter. Additionally, the Lyot filter arrangement and the laser gain material are strategically placed in different branches of the folded cavity.
Another significant patent is for a Q-Switched Laser. This microchip laser arrangement is designed to emit Q-switched laser pulses at a wavelength of 1.54 µm. The lasing medium consists of Yb:Er-glass, while the Q-switch employs a saturable absorber made of cobalt-doped spinel crystal. The design integrates the lasing medium and the absorber into a monolithic body, with dielectric stacks forming a resonant laser cavity. The active medium is pumped using an InGaAs laser diode that emits light at 0.97 µm, which aligns well with the absorption characteristics of the Yb:Er-glass material.
