Passat Ltd. is a Canadian company specializing in the design and manufacture of diode-pumped solid-state lasers (DPSS) and related optical components.[1] Established in 1995, the company is headquartered in Vaughan, Ontario, and serves clients worldwide across various industries, including aerospace, electronics, and materials processing.

History

[edit]

Passat Ltd. was founded in 1995 with a focus on developing compact, all-solid-state picosecond[2] DPSS lasers. Over the years, the company has expanded its product line to include sub-nanosecond lasers[3], custom laser systems, and optical components such as Faraday rotators and isolators. Passat's lasers have been supplied to over 30 countries and have been utilized in applications ranging from materials processing to scientific research.[4]

Products and services

[edit]

Diode-Pumped Solid-State Lasers

Passat offers a range of DPSS lasers, including picosecond and sub-nanosecond models. These lasers cover a spectral range from deep ultraviolet (213 nm, 266 nm, 355 nm) to eye-safe wavelengths (1.6 µm). Notable products include the "Compiler" series and "Sub-Naples" lasers, known for their high peak power and compact design[5].

Faraday Rotators and Isolators

The company manufactures Faraday rotators and isolators characterized by their compact size, high transparency, and extinction ratios of 35–40 dB. High-power, cooled models are also available.[6]

Laser Micromachining Services

Passat provides laser micromachining services, including drilling, milling, scribing, and patterning. The company specializes in creating micro-holes with large depth-to-diameter ratios in various materials. Additionally, Passat offers rental services for its DPSS lasers[7].[8]

Applications

[edit]

Passat Ltd. specializes in laser micromachining services, utilizing diode-pumped solid-state (DPSS) lasers to process a variety of materials with high precision. Their applications include:[9]

  • Laser Micro-Drilling: Creating micro-holes in various materials for use as high-precision pinholes, nozzles, orifices, and vias. Passat Lasers
  • Laser Micro-Milling: Producing fine features in materials, ideal for manufacturing micro-moulds, micro-stamping tools, and microfluidic devices.
  • Laser Micro-Scribing: Scribing fine slots in materials such as ceramics, silicon, sapphire, metals, and glass. These slots are applicable in processes like the Laser Groove Buried Grid (LGBG) used in photovoltaic cell production.
  • Laser Micro-Patterning: Engraving patterns or shapes onto various materials by scanning the laser beam over the surface to remove small amounts of material per pulse.

Additionally, Passat Ltd.'s Compiler series of high-energy DPSS picosecond lasers are utilized in various advanced applications:[10]

  • Photoionization: Ionizing atoms or molecules using laser photons for analytical applications.
  • Laser-Induced Breakdown Spectroscopy (LIBS): Analyzing the composition of materials by observing the light emitted from a plasma generated by laser pulses.
  • Laser Ablation, Fragmentation, and Destruction: Removing material from a solid surface by irradiating it with a laser beam.
  • Photolithography: Transferring geometric patterns onto a substrate using light, commonly used in semiconductor manufacturing.
  • Laser-Induced Fluorescence (LIF): Detecting and analyzing the fluorescence emitted by a substance after it has absorbed laser light.
  • Raman Spectroscopy: Studying vibrational, rotational, and other low-frequency modes in a system using laser light scattering.
  • Time-Resolved Spectroscopy: Observing the evolution of a system over time after it has been excited by a laser pulse.
  • Remote Sensing: Collecting information about objects or areas from a distance, often using laser-based technologies like LIDAR[11]
  • Medical and Biomedical Research: Applying laser technologies in medical diagnostics, treatment, and research.
  • Photo-Acoustic Imaging: Combining laser-induced ultrasound with imaging techniques for medical diagnostics.
Certificate of Recognition for outstanding performance and lasting contribution to the success of the Phoenix MET Instrument

Notable Projects

[edit]
  • Phoenix Mars Mission (2008): Passat Ltd. contributed to the Canadian Space Agency's involvement in NASA's Phoenix Mars Lander mission by providing expertise in laser technology, supporting the development of the Meteorological Station's lidar instrument. This instrument was pivotal in detecting snow in the Martian atmosphere, marking a significant milestone in planetary science.[12]
  • Canadian Space Agency Lidar Project (2009): In collaboration with the Canadian Space Agency (CSA), Passat Ltd. received a $200,000 contract to develop the conceptual design for a space-borne lidar (Light Detection and Ranging) system using picosecond laser pulses. The goal of this project was to enable high-resolution three-dimensional Earth observation by significantly enhancing the spatial and temporal accuracy of remote sensing instruments. This work contributed to the development of advanced photonics solutions for space-based atmospheric and surface studies.[13]
