HÜBNER Photonics Introduces the C-WAVE BTS

HÜBNER Photonics has announced the launch of the C-WAVE BTS, which is a continuous-wave (CW), single-frequency titanium:sapphire laser designed to deliver tunable output from 700 nm to 1000 nm with power levels up to 4 W.¹ According to the company, this new system is designed to expand the company’s C-WAVE laser portfolio and targets spectroscopy and quantum research applications that require stable, high-power, narrow-linewidth light across the near-infrared (NIR) region.¹

According to the manufacturer, the C-WAVE BTS (Broadband Titanium Sapphire) combines watt-level output with automated wavelength tuning and alignment, enabling researchers to adjust excitation wavelengths across its tuning range.¹ The platform builds on the hardware architecture used in existing C-WAVE systems deployed in academic and industrial laboratories, emphasizing long-term stability and minimal user intervention.

The launch complements the established C-WAVE VIS and C-WAVE GTR models, which use optical parametric oscillator (OPO) technology to span shorter and longer wavelengths.¹ Together with the new Ti:sapphire-based BTS model, the C-WAVE family now covers wavelengths from approximately 450 nm to 3.4 µm, providing single-frequency CW tunable output across the visible and into the infrared (IR) region.¹ According to the company, this range represents one of the broadest wavelength coverages available from a single-frequency CW tunable laser platform.¹

HÜBNER Photonics positions the C-WAVE BTS for advanced spectroscopy, particularly resonant Raman spectroscopy, where precise wavelength selection and high optical power can enhance signal strength and selectivity.¹ The source is also intended for studies of quantum materials and other photonics experiments requiring narrow linewidth and stable frequency output in the near-infrared (NIR).

The original C-WAVE platform received a PRISM Award from the photonics industry for innovation in tunable CW laser technology, and the BTS model extends that design philosophy into the Ti:sapphire domain.¹ By integrating automated tuning and system control, the company aims to reduce setup complexity and allow users to focus on experimental workflows rather than laser optimization.
