Lasers

Image for More Blue in the Lab at 447 nm

The Xiton Photonics Research and Development Team have produced new gorgeous laser results in the lab. Three types of lasers are available with different repetition rate, power,​​ and stability:

  • 30 kHz repetition rate at 7 watt and 447​​ nm with​​ less than 3% pulse fluctuation

  • 50 kHz repetition rate at 5 Watt and 447​​ nm with​​ less than 4% pulse fluctuation

  • 100 kHz repetition rate at 2 Watt and 447​​ nm with​​ less than 10% pulse fluctuation

University researchers​​ and​​ MegaWatt Lasers​​ presented a paper about flash lamp-pumped CTH:YAG master oscillator power amplifiers (MOPA).

The title of the paper is “Electro-optically Q-switched 2.8 um Cr:Er:YSGG laser with output energy up to 300 mJ.” Here is the paper’s abstract:

For some medical and remote sensing applications, high peak power and high energy per pulse laser emission in the 2 µm is required. We report results using a flash lamp-pumped CTH:YAG MOPA configura-tion where we achieved 500 mJ output at 5 Hz with a 50 ns pulse duration.

Xiton Photonics produces lasers providing 671 nm red light. Three types of lasers are available with different repetition rate, power,​​ and stability:

  • 30 kHz repetition rate at 9 watt and 671 nm with less than 2% pulse fluctuation

  • 50 kHz repetition rate at 7 watt and 671 nm with less than 3% pulse fluctuation

  • 100 kHz repetition rate at 5 watt and 671 nm with less than 7% pulse fluctuation

Optics

In the semiconductor industry, extremely small surface defects and particles are a major concern that reduces yield and also costs producers time and money. It is therefore critical to inspect the surface of semiconductor wafers for defects and contamination, a challenge many of Holo/Or’s​​ customers in the semiconductor metrology industry face.

Holo/Or have many years of experience with laser line generator optics for wafer inspection and metrology. Contact Holo/Or with your requirements and they will be happy to support you.

Image for Starter Optic Kits

Customers of MegaWatt Lasers (MWL) have expressed interest in optical kits for the most common resonator setups. In response, MWL are happy to announce the release of a 1064-nm Nd:YAG Starter Optics Kit.

These kits are designed with an R&D focus and are all tested in house. All optics are 0.5” x 0.25” (12.7 mm x 6.35​​ mm) fused silica with a high damage threshold.

Tony Hallas has shared another great photo! This is a picture of M78, a reflection nebula in the constellation Orion. This image was captured using​​ Chroma Technology RGB astronomy filters and Ha astronomy filters.

Image for Beam Sampler for Laser Process Monitoring

Have you tried​​ Holo/Or’s​​ beam samplers​​ for laser process monitoring?

These simple, robust grating-like DOEs are coated with high LDT AR coating and can handle high power densities and ultrashort (including fs) pulses. Diffractive samplers have multiple orders that can be used for sampling the beam with various ratios. For example, the first order can sample 0.2% of input beam, with the third order sampling 0.02% of the input laser. This enables the use of both power meter and camera in a multi-kW laser setup, with each order going to the appropriate sensor.

Contact Holo/Or​​ for more information.
