New tunable mid-infrared solution | Holmium / Chromium solid-state laser, covering 2.04–2.9μm

New Mid-Infrared Tunable Solution | Rayever Holmium/Chromium Solid-State Lasers Covering Full 2.04–2.9 μm Band

The 2–3 μm mid-infrared waveband is a core window for medical aesthetics, spectral detection, and nonlinear optics research. Conventional lasers often suffer incomplete waveband coverage, bulky overall size and poor beam stability. Rayever launches the brand-new Holmium/Chromium Solid-State Lasers. Supported by self-developed thulium fiber pumping technology, they deliver wide-range continuously tunable output to meet mid-infrared application demands across multiple industries with one-stop solutions.

1. Dual Series Covering the Complete 2.04–2.9 μm Mid-Infrared Range

The product line includes two series: Ho-xx Holmium Lasers and Cr-xx Chromium Lasers, with clearly divided parameters for easy model selection.

Seamless coverage from 2.04 μm to 2.9 μm. It satisfies both short mid-infrared 2.1 μm scenarios and long mid-infrared 2.2–2.9 μm requirements, eliminating high costs from deploying multiple separate laser devices.

2. Core Technical Advantages Over Traditional Solid-State Lasers

1. Thulium Fiber Laser Pump ArchitectureAbandons cumbersome lamp-pumped and solid-state pumped schemes. The fiber-pumped structure drastically reduces overall laser footprint, lowering integration difficulty for embedding into medical equipment, LiDAR systems, and online monitoring instruments.

2. Wide-Band Continuously Tunable OutputContinuous wavelength tuning is realized within a single laser unit without replacing resonant cavity components, greatly improving wavelength switching efficiency for spectral experiments and atmospheric gas monitoring.

3. Superior Beam Quality & High Conversion EfficiencyOptimized resonant cavity design delivers uniform beam profile and low energy conversion loss. The ±1% power stability ensures negligible energy drift during long-hour continuous operation, ideal for high-precision machining and delicate scientific research experiments.

4. Integrated High-Reliability ChassisModular sealed housing with excellent vibration resistance and temperature drift suppression, enabling stable long-term operation in industrial sites, laboratories, and mobile airborne scenarios.

3. Wide Range of Application Scenarios

Medical & Aesthetic Treatment

The 2.1 μm and 2.7–2.9 μm bands feature outstanding absorption in water-rich human tissues, suitable for minimally invasive ablation in urology, dental surgery, skin aesthetic repair and soft tissue cutting. Pulsed mode enables precise thermal control to reduce post-operation trauma.

Precision Industrial Processing

Ideal for micro-etching, drilling and cutting of polymers, ceramics and biomaterials with minimal thermal damage.

Environmental Monitoring & LiDAR

Full coverage of characteristic absorption peaks of mid-infrared gases for online detection of greenhouse gases and VOCs. Airborne/vehicle-mounted mid-infrared LiDAR supports atmospheric remote ranging and pollutant tomographic detection.

Spectroscopy & Nonlinear Optics Research

Tunable light source for absorption/fluorescence spectrum testing. Can serve as a high-performance pump source for nonlinear frequency conversion systems such as OPO and DFG, supporting cutting-edge research on infrared and terahertz technologies.

4. Customization Services Available

Rayever provides full parameter non-standard customization:

• Custom output power, pulse repetition frequency and pulse width

• Two output interfaces: fiber-coupled or free-space

• Custom chassis dimensions, water-cooled / air-cooled heat dissipation for customer equipment integration

• Integrated delivery of matching drive control systems and upper computer software

Demand for mid-infrared lasers keeps surging. Our compact, highly stable solid-state laser covering the full 2–3 μm wide band caters to both mass-produced commercial equipment and cutting-edge research projects. Rayever Holmium/Chromium Solid-State Lasers deliver a one-stop solution for mid-infrared light source selection.
